Beneath is a guide to using SteamPipe, Valve'due south tool for delivering content to Steam. For more data on all-time practices for updating your game, see Updating Your Game - Best Practices.

Introduction to the SteamPipe Content System

SteamPipe is the game/application content organization that powers Steam. SteamPipe includes the following features:

• Efficient and fast content delivery.
  
• Public and private "beta" branches, allowing multiple builds to be tested.
  
• Simple spider web-based management of builds - push out a new build or rollback to a previous build with but a few clicks.
  
• Power to encounter the update size of a build before setting information technology live.
  
• Ability to share content between multiple applications.
  
• Power to build installer discs from public or beta content.
  
• Games/apps stay available offline fifty-fifty subsequently an update download has been started.
  
• All content is always encrypted, and non-active versions are not visible to customers.
  
• A SteamPipe Local Content Server which can be used during development.

NOTE: There are a few concepts which are integral to SteamPipe, earlier getting started yous should be familiar with all of the concepts outlined in the Applications documentation. Having even a basic understanding of how these pieces fit together will exist very useful when uploading your product to Steam.

SteamPipe Technical Details

SteamPipe uses the HTTP protocol for content commitment. Since downloads are regular web traffic, any third-political party HTTP cache between the client and Steam servers will increment download speed. Content can be hosted by external CDN providers, which tin can be easily added to our content network. Most consumer firewalls allow HTTP traffic and won't cake downloads.

SteamPipe has an efficient patching algorithm based on binary deltas, simply changing the modified portions of existing content files. When this content is updated, only these deltas demand be sent. This means both developer and user transfers are smaller and faster. Most partners volition discover that using a SteamPipe Local Content Server not necessary since they can efficiently patch builds on private branches.

Steam Build Account

Before you can create whatsoever builds on Steam, you must have a Steam account in your Steamworks account with the "Edit App Metadata" and "Publish App Changes To Steam" permissions granted. For security reasons it's recommended that you have a dedicated build account with only those permissions, you may create a new Steam account for this purpose at https://shop.steampowered.com/join.

Whatsoever administrator of your Steamworks account can add a Steam account and grant the necessary permissions. More than information on this process tin exist constitute in the Managing Your Steamworks Business relationship documentation. An example of what this business relationship might look like is:

Initial Setup for New SteamPipe Apps

Follow these steps to set upwards new SteamPipe apps:

1. Find the app ID for your application (this can be institute by selecting the application on your homepage in Steamworks)
   
2. Go to the General Installation Settings page for your app.
   
3. Ascertain at least one launch pick (the path and optionally, any arguments required to launch the game). Hover over the (?) to learn more near each field.

   The case below shows 5 launch options, 2 for Windows, 2 for macOS and 1 for Linux.
   Launch selection three will but be shown on Windows if the user also owns the DLC specified.

   

4. Go to the Depots page and add together depots equally needed for this app. Past default, a depot may already exist configured for your application.
   
   1. Click the default depot and alter the name of the depot to a proper and recognizable name (such as "Base Content" or "Windows Content").
      
   2. Leave the language gear up to [All languages] unless this is a language-specific depot.
      
   3. Get out the Bone set to [All OSes] unless this is an Os-specific depot (if the app is all-in-one, or is but PC or simply Mac, it should be left to [All OSes]. But specify for Bone-specific game depots.
      
   4. Click Add together New Depot to create additional depots.
      
   5. Click Salvage Changes to salvage any changes made.
      
5. In one case you are done defining your depots, publish the changes that you accept made from the Publish page.
   
6. Your newly defined depots volition demand to be included in a bundle to grant you lot ownership of them. Each game on Steam should have a Developer Comp package which is automatically granted to the accounts listed within your publisher group.
   You lot can add the new depots to that package (and/or other packages that should take these depots) on the Associated Packages & DLC page.

Annotation: If your executable is in a sub-folder of the main installation binder, add together the sub-folder name in the Executable field. Don't use leading slashes or dots.

Platform Note: As shown above, macOS applications may be launched by specifying either an app bundle (Game.app) or a script/binary (Game.app/Contents/MacOS/Game). In general the app bundle format should be preferred if possible as information technology allows macOS to more than correctly determine launch parameters in the manner it would if launched manually outside of Steam.

One case of this to annotation is that currently applications that are launched through an app bundle on Apple tree Silicon devices volition launch the best architecture available in the application whereas direct binary launches volition utilise the aforementioned compages every bit the Steam procedure (currently x86_64).

Setting upward the SDK for SteamPipe uploads

Download and unzip the latest version of the Steamworks SDK on the machine you will be uploading builds on.

The SteamPipe tools can be found within the SDK in the tools folder which contains ii relevant sub-directories.

The ContentBuilder directory is where your game content and SteamPipe build tools will live. This directory contains the post-obit sub-directories:

• architect - This directory initially contains merely steamcmd.exe which is the command line version of Steam.
  
• builder_linux - The linux version of steamcmd.
  
• builder_osx - The macOS version of steamcmd.
  
• content - This directory contains all game files that volition be built into depots.
  
• output - This directory will be the location for build logs, chunk enshroud, and intermediate output. Notation: This binder tin be deleted or emptied at any time, but after it'south deleted, the side by side upload time will take longer.
  
• scripts - This directory is where you lot'll identify all of your build scripts for edifice your game depots.

Information technology'southward recommended that you run steamcmd.exe straight in the builder folder for your platform once to bootstrap your build arrangement. This should populate your architect directory with all the files it needs to build depots.

The ContentServer directory contains the tools for running your own SteamPipe Local Content Server if you cull to practice so.

SteamCmd on macOS

To enable SteamCmd on macOS you must complete the following steps:

1. From the terminal, browse to the tools\ContentBuilder\builder_osx\osx32 binder
   
2. Run chmod +ten steamcmd
   
3. Browse upwardly to the parent folder (tools\ContentBuilder\builder_osx)
   
4. Type fustigate ./steamcmd.sh
   
5. SteamCmd volition then run and update to the latest build, leaving you in the SteamCmd prompt
   
6. Type exit and printing render to exit the prompt

Yous can and then follow the residue of this documentation (substituting paths equally appropriate) to create depot and app config files for uploading your content to Steam.

Creating SteamPipe Build Config Files

To upload files for your app with SteamPipe, you must create scripts which describe your build and each depot that will be included in information technology. The example scripts shown here are in the Tools\ContentBuilder\scripts folder in the Steamworks SDK.

SteamPipe GUI Tool

If you're running on Windows and would prefer a GUI tool to assistance create these config files and upload your builds you tin use the SteamPipeGUI which is available in the tools folder of the Steamworks SDK. Included in the aught are additional instructions to get you started.

If y'all choose to employ the GUI tool and then reading the following sections is even so recommended to help y'all get more familiar with how the SteamPipe system works.

Simple Build Script

Let's start with the most basic build script possible. In our example nosotros have a game (AppID 1000) that has ane depot (DepotID 1001) and want to upload all files from a content folder and it'south subfolders. We but demand a single build script for that, take a look at "simple_app_build.vdf" included in the SDK :

"AppBuild" { "AppID" "1000" // your AppID "Desc" "This is a simple build script" // internal description for this build "ContentRoot" "..\content\" // root content folder, relative to location of this file "BuildOutput" "..\output\" // build output folder for build logs and build cache files "Depots" { "1001" // your DepotID { "FileMapping" { "LocalPath" "*" // all files from contentroot folder "DepotPath" "." // mapped into the root of the depot "recursive" "ane" // include all subfolders } } } }

Accommodate the AppID and DepotID for your game equally needed. To kick off a build you need to run steamcmd and laissez passer a couple of parameters :

tools\ContentBuilder\builder\steamcmd.exe +login <account_name> <password> +run_app_build ..\scripts\simple_app_build.vdf +quit

NOTE: Your beginning effort at running a build may fail due to Steam Guard. If the login fails due to Steam Guard, check your email for the Steam Guard code, and run steamcmd as: steamcmd.exe "set_steam_guard_code <code>", and try again. Afterward logging in with Steam Guard once, a sentry file is used to verify the login is genuine.

If you are using steamcmd from a machine or VM that gets re-imaged frequently, y'all should include the lookout man and config file in your paradigm so you won't be prompted for a Steam Baby-sit every fourth dimension. The lookout file is located in <Steam>\ssfn<hashOfNumbers>, and the config file is located in <Steam>\config\config.vdf.

The following steps occur during a SteamPipe build:

1. Steamcmd.exe volition update itself to the latest version.
   
2. Steamcmd.exe is logging into the Steam backend using the given builder Steam business relationship.
   
3. The app build start is registered with the MDS (Master Depot Server), which volition ensure the user has the proper privileges to change this app.
   
4. For each depot included in the app build, a file list is generated based on the files in the content folder and the filter rules defined in depot build config file.
   
5. Each file is scanned and divided into modest chunks of about 1MB. If the depot has been congenital before, this partitioning will preserve as many of the unchanged chunks equally possible.
   
6. New file chunks are compressed, encrypted, and so uploaded to the MDS.
   
7. A final manifest is generated for this depot version; each manifest is identified by a unique 64-bit manifest ID.
   
8. Once all depots have been processed, the MDS finishes this app build and assigns it a global BuildID.
   
9. Subsequently the build is done, at that place may exist *.csm and *.csd files in the build ouput folder. These are temporary and tin exist deleted, but they speed up subsequent build times.

One time the build is complete you tin meet information technology on your app builds folio, in this instance it would be https://partner.steamgames.com/apps/builds/one thousand. There you tin set that build alive for the default branch or any beta branch and users will be able to download this update with a couple of minutes.

Advanced Build Scripts

If your app has a lot of depots with complex file mapping rules, you lot can create a depot build script for each depot which will exist referenced by the app build script. Commencement allow's accept a look at bachelor parameters in the app build script:

• AppID - The AppID of your game. The uploading Steam partner account needs 'Edit App Metadata' privileges
  
• Desc - The clarification is only visible to you in the 'Your Builds' department of the App Admin console. This can exist changed at whatsoever time afterwards uploading a build on the 'Your Builds' page.
  
• ContentRoot - The root binder of your game files, can be an absolute path or relative to the build script file.
  
• BuildOutput - This directory will be the location for build logs, depot manifests, chunk caches, and intermediate output. For best performance, use a separate deejay for your build output. This splits the disk IO workload, letting your content root disk handle the read requests and your output disk handle the write requests.
  
• Preview - This type of build only outputs logs and a file manifest into the build output folder. Building preview builds is a good way to iterate on your upload scripts and brand certain your file mappings, filters and properties work as intended.
  
• Local - Set this to the htdocs path of your SteamPipe Local Content Server (LCS). LCS builds put content merely on your own HTTP server and allow you to examination the installation of your game using the Steam customer.
  
• SetLive - Beta branch name to automatically set alive after successful build, none if empty. Annotation that the 'default' co-operative can not exist prepare alive automatically. That must exist washed through the App Admin panel.
  
• Depots - This section contains all file mappings, filters and file properties for each depot or references a separate script file for each depot

Case app build script "app_build_1000.vdf" is using all options:

"AppBuild" { "AppID" "1000" // Your AppID "Desc" "Your build description here" // internal description for this build "Preview" "ane" // make this a preview build only, nothing is uploaded "Local" "..\..\ContentServer\htdocs" // put content on local content server instead of uploading to Steam "SetLive" "AlphaTest" // gear up this build live on a beta co-operative "ContentRoot" "..\content\" // content root folder relative to this script file "BuildOutput" "D:\build_output\" // put build cache and log files on unlike drive for better functioning "Depots" { // file mapping instructions for each depot are in separate script files "1001" "depot_build_1001.vdf" "1002" "depot_build_1002.vdf" } }

This app build script references two depot build script files that specify all file mappings and file properties. The post-obit instructions are available in a depot build script ( and as well if the section is included directly into the app build script).

• DepotID - The DepotID for this section
  
• ContentRoot - Lets you optionally override the ContentRoot folder from the app build script on a per depot footing
  
• FileMapping - This maps a single file or a set of files from the local content root into your depot. In that location can be multiple file mappings that add files to the depot. The LocalPath parameter is a relative path to the content root folder and may contain wildcards like '?' or '*'. Information technology will likewise apply to matching files in subfolders if Recursive is enabled. The DepotPath parameter specifies where the selected files should appear in the depot (use just '.' for no special mapping)
  
• FileExclusion - will excluded mapped files over again and can also contain wildcards like '?' or '*'
  
• InstallScript - will marker a file as install scripts and will sign the file during the build process. The Steam client knows to run them for any awarding which mounts this depot.
  
• FileProperties - will mark a file with special flags:
  
  • userconfig - This file is modified by the user or game. It cannot be overridden by an update, and it won't trigger a verification error if it's different from the previous version of the file.
    
  • versionedconfig - Similar to userconfig, however if the file is updated in the depot, it will be overwritten locally when the user's game updates. Simply update the file in the depot when at that place is a necessary format change or problems set.

Example depot build script depot_build_1002.vdf showing apply of all options:

"DepotBuild" { "DepotID" "1002" "ContentRoot" "C:\content\depot1002" // override ContentRoot from app build script "FileMapping" { // all source files and folders in ".\bin" will be mapped into folder ".\executables" in depot "LocalPath" "bin\*" "DepotPath" "executables\" "Recursive" "ane" // include all subfolders } "FileMapping" { // override sound files in \\sound with German versions "LocalPath" "localization\german\audio\*" "DepotPath" "audio\" } "FileMapping" { // re-create install script for german version into depot root binder "LocalPath" "localization\german\german_installscript.vdf" "DepotPath" "." } "FileExclusion" "bin\server.exe" // exclude this file "FileExclusion" "*.pdb" // exclude all .PDB files everywhere "FileExclusion" "bin\tools*" // exclude all files under bin\tools\ "InstallScript" "localization\german\german_installscript.vdf" "FileProperties" { "LocalPath" "bin\setup.cfg" "Attributes" "userconfig" // this file will be modified during runtime } }

NOTE: You lot tin can name these scripts what ever you want, but we utilise the names app_build_<AppID> and depot_build_<DepotID> for consistency. If you know that you'll be building apps on this machine, it might be a good thought to create sub-directories in your scripts directory for each application, to help organize each awarding'southward build scripts.

Managing Updates

Subsequently your app releases to customers, your customers will be receiving the build marked equally the Default build. When uploading a new build it's ever a good idea to test information technology before aircraft information technology to your customers, for more data on how to successfully exercise this encounter Testing On Steam.

Debugging Build Issues

If your build wasn't successful, you should look in your output directory for fault information, not the panel where the build script was run. Most error information tin can be constitute in the *.log files.
You lot can utilise these Steam client commands and customer-side files to debug issues:

• "app_status [appid]" - Shows the current state of the app on this client.
  
• "app_info_print [appid]" - Shows the current Steamworks configuration for this game (depots, launch options, etc.).
  
• "app_config_print [appid]" - Shows the current user configuration for this game (electric current linguistic communication, install directory, etc.).
  
• file "logs\content_log.txt" - Lists all logged SteamPipe operations and errors.
  
• file "steamapps\appmanifest_[appid].acf" - Shows the current install state of this app (KeyValues).

Building Efficient Depots for SteamPipe

The erstwhile Steam content organization would patch updates on a file level, which meant that if a single byte in a file inverse, the entire new file would exist downloaded by all users. This was peculiarly inefficient if the game used pack files, which are collections of game content files in a single big file. Pack files can hands exceed i GB, so updates often led to unnecessarily large downloads. A common way to avoid these large downloads was to add new pack files that overrode content of already shipped pack files. That worked for updates, but information technology injure new users long-term, since they ended up downloading unused, already-patched content.

The new content arrangement fixes this problem by splitting each file into roughly ane-MB chunks. Each chunk is then compressed and encrypted before existence distributed past the Steam content arrangement. If the game content has large redundant parts, these chunks are reused and the user but has to download each repeated chunk in one case. However, the real strength of this system is building efficient update patches. While the arrangement is building a patch, the new content is scanned for already known chunks. If it finds them, it reuses them. This means if you change or inject a few bytes in a large file, the user just has to download the changes.

This works well in most cases, but there are notwithstanding a few pitfalls that need to be avoided when designing the content layout of a game. You may not desire to compress or encrypt your game data. This is already done for in-flight downloads and retail discs by the Steam content organization. If you do it besides, it tin reduce the effectiveness of delta patching. Compression and encryption are merely advised if each private asset within a parcel file is separately compressed and/or encrypted. Otherwise, a change to one asset volition always crave downloading several other potentially unchanged assets.

If yous parcel multiple assets in a pack file, make sure that with each re-packaging, no unnecessary changes are made. One problematic practise is including the full name of the original source files on deejay, because the names may change, depending on the build machine. Another bad pattern is including build time stamps for each file. If possible, always add new content to the terminate of your pack files and keep the social club of existing files. Also, keep your pack file'southward metadata (offset and sizes to individual assets) in ane identify and don't intersperse it with the nugget data. Use a binary departure tool like BeyondCompare to wait at two builds of your pack files to make certain that hundreds of unwanted changes don't show up.

Using pack files is especially useful to package lots of modest files (<i MB) into a single larger file. This will meliorate download speed and disk IO performance. Merely yous might also want to avoid to put all your assets in a single huge pack file since Steam needs to copy & patch the whole file even if merely a small subset of it inverse. A skillful outset would be to bundle resources of the same type together in pack files smaller than 4GB each.

If you follow these rules you volition minimize patch sizes and merely new content will demand to be downloaded. Your customers will thank you for that and you will be able to increase the quality of your product by shipping more than updates.

If you suspect that your game packaging is not interacting well with the SteamPipe update procedure, please contact your Valve representative and we can look into enabling advanced features to help with this.

Building Retail Install Discs

To build retail install disc for SteamPipe games, you lot must start setup a build project file.
In this example, the SKU file is called "sku_goldmaster.txt":

"sku" { "proper noun" "Test Game Installer" "appid" "202930" "disk_size_mb" "640" "included_depots" { "1" "202931" "two" "202932" } }

Some tips to proceed in listen:

• Create a new folder where the retail disc images will exist written to, e.one thousand., "D:\retail_disks". Only depots in the included_depots sections are added; in that location is no exclude section anymore.
  
• You can utilize Steam.exe (with the -dev and -console control-line parameters) or steamcmd.exe to build installer images. In both cases, apply the "build_installer" command.
  
• Log on with a Steam account that owns the game and all depots you want to put on the retail disc. Otherwise, the account doesn't need special rights, so anyone can build installer discs.
  
• If you use Steam.exe, end all other downloads.
  
• Go to the console page and run the build_installer command:

  build_installer sku_goldmaster.txt "D:\retail_disks"

  The build tin can accept a while since all depots are re-downloaded the first fourth dimension.
  
• If you lot're building a GM using a local content server, run:
  @localcontentserver "webserver"
build_installer sku_goldmaster.txt "D:\retail_disks" local
  The spew refers to 'Backup' since 'Retail install Disk' and local game backups are basically the aforementioned.
  
• Once yous see "Backup finished for AppID...", the install disk images are set up. You can find more details about the fill-in build in logs\backup_log.txt.
  
• There are new folders (Disk_1, Disk_2, and so on) in "D:\retail_disks", each not bigger than 640 MB, as specified with "disk_size_mb". Each disk folder contains a "sku.sis" file and a .csd and .csm for each depot. Bigger depots span beyond multiple disks. All retail install deejay content is always encrypted (unlike local game backup files). Re-create the SDK GM setup files (setup.exe, setup.ini, etc.) into the folder of your commencement disk and the retail disc installer is complete.
  
• When creating a GM for macOS be sure to open the goldmaster/disk_assets/SteamRetailInstaller.dmg image on a Mac. And so take the app that is in there and copy information technology to the root of your media. Y'all will probably want to modify the proper name of the install app, brand the icon and decorate the window to only show the installer.
  
• When creating a multi-disc GM for macOS, be sure the book name for each disc matches. The volume name becomes part of the mount path, and if the names don't match the installer won't be able to find the next disc.

Optionally edifice a retail installer from a beta branch

The process above will create a retail installer based on the default branch. If you need to create an installer based on a beta branch, you must first create a beta branch named "baseline". So use the following command to build from the baseline branch:

build_installer <projection file> <target folder> <beta cardinal> <beta pwd> steamcmd ex: build_installer sku_goldmaster.txt "D:\retail_disks" baseline superSecret script ex: steamcmd.exe +login user_name password +build_installer "..\Build\GameDataSku.txt" c:\destination beta_key beta_password +exit

Installing DLC from a retail installer

In some circumstances, yous may wish to create a retail installer that includes your DLC packages. In such cases, the process to create the installer requires simply a few changes.
In "sku_goldmaster.txt", include the DLC AppIDs nether the "included_depots" section. Once you take run the "build_installer" procedure, find the generated sku.sister file for the installer and open it with a text editor.
Add together the DLC AppID in the "apps" section. For example, if I had a game with AppID 1000 and DLC AppID 1010, I would suit the "apps" section as follows:

"apps" { "0" "1000" "1" "1010" }

This will ensure that Steam checks for ownership of the DLC and prompt the user for a cardinal if the DLC is not endemic by the account that they are logging into on Steam.

Building a retail installer for multiple App IDs on a single disc/install parcel

To build a GM containing multiple Steam Pipage apps. Build each app installer i by 1 but point them all to the aforementioned output folder. Each build will merge itself with the already existing install prototype.

Customizing a Retail install disk

Encounter Customizing a gold master for more details on customizing your retail install disk.

Preloading Games earlier Release

By default, all content is ever encrypted, on all retail discs and on all content servers. Switching a game to preload way means owners tin download the content, simply it stays encrypted on the users' disk and tin can't be played. Once the game becomes officially released, Steam will decrypt the preloaded content and the user tin play the game.

Switching a game to preload mode is recommended in these cases:

• Shipping retail discs with product keys before the game is actually available (0-twenty-four hour period piracy).
  
• Games that run a pre-purchase and are larger than 20GBs in size.

Please submit a ticket to Steam Publishing if you believe your game requires preloading.

Edifice DLC

DLC is built as a depot of the base game. See the Downloadable Content (DLC) documentation for more than data.

Troubleshooting SteamPipe

"Login Failure: Business relationship Login Denied Failed" when logging in via steamcmd

Cause: Probably SteamGuard is preventing login. Resolution:

• Check the email associated with the account you are trying to log on with and look for an email from Steam Back up. Copy the code from that email.
  
• Run the following steamcmd: set_steam_guard_code <lawmaking>
  
• Re-Attempt login from steamcmd: Steam>login <buildaccount> <password>

Full general Troubleshooting for Download Bug

• Restart calculator, modem, router, etc.
  
• Verify firewall settings. The new system requires port 80 (HTTP) and all other Steam ports, listed hither.
  
• Temporarily disable local Anti-Virus or Spam-Blocker programs.
  
• Bank check the Steam download region under Settings->Downloads. It should match your location.
  
• Stop the download, uninstall, and reinstall the game (clear manifest caches).
  
• Leave Steam, delete the ii folders appcache and depotcache in your Steam install folder.
  
• Try to set your Steam download region to some other location far away. This might piece of work if a content server most you lot is serving bad information.

My Mac and/or Linux Builds aren't installing any files. Why?

If you're testing via Steam the installation of your game or application across multiple platforms, you may encounter a situation where the build deploys on Windows but doesn't deploy any files on Mac or Linux despite your SteamPipe procedure being setup to upload Mac and/or Linux depots. In that location is a footstep that is easily missed which involves adding your alternating Depots to the Package being deployed. You can check what depots are included in a package via the following steps:

1. Navigate to your App Admin page
   
2. From the View Associated Items section, click All Associated Packages, DLC, Demos and Tools.
   
3. Click on the title of the Packet you're attempting to download
   
4. Review the Depots Included department
   
5. Utilise the Add/Remove Depots to ensure the correct set of Depots are assigned to the Packet

There are a number of discussion threads about this that may also assist:

• Empty folder after installing the game
  
• Unity Builds for PC/Mac/Linux
  
• Preparing Content for Mac Packaging

Running steamcmd.exe results in the following error: "SteamUpdater: Fault: Steam needs to be online to update. Please confirm your network connectedness and effort again."

Resolution: Become to Internet Options->Connections->Lan Settings and check Automatically discover settings.

Running the app build results in the post-obit error: "ERROR! Failed 'DepotBuild for scriptname.vdf' - status = six."

Possible Causes:

• Account does non have permissions for the app.
  
  • Check that the app ID is right in the app_build.vdf.
    
  • Check that the build business relationship has proper permissions to the app ID.
    
• Steamcmd cannot notice the depot contents.
  
  • Cheque that the "contentroot" value in the app_build script is a valid path relative to the location of the script file.
    
  • Bank check that the "LocalPath" value in the depot_build script is a valid path relative to the path in the app_build script. Bank check that the path contains actual content.
    

Running the app build results in the following error: "ERROR! Failed to get awarding info for app NNNNN (check login and subscription)"

This means that Steam can't retrieve information about the app, either because information technology doesn't exist or the user doesn't have admission to the app.

• Check that the NNNNN is the app ID you were assigned for the app.
  
• Check that the app ID is correct in the app_build.vdf.
  
• If it is a new app ID, check that the Steamworks app admin configuration has been published. New apps should have a Steam Pipe install directory on the config tab, a depot on the depot tab, and all changes published on the publish tab.
  
• If all of that looks right, make sure that your account owns the app ID.

"An error occurred while installing [AppName] (Invalid content configuration)" at launch time

Possible Causes:

• No build has been set live on the branch yous're trying to install from.
  Resolution: Set your build live on a branch by going to https://partner.steamgames.com/apps/builds/<YourGameAppId>, and select that co-operative in the Steam customer (equally described hither).
  
• Invalid game launch options.
  Resolution: Verify the launch options on the Installation tab in the app admin for your game https://partner.steamgames.com/apps/config/<YourGameAppId>.
  
• You lot don't own the Depot IDs that make up the game.
  Resolution: Make sure the necessary depots are added to the development subscription (Meet Editing packages for additional details).

"Error lawmaking 15" at launch time

This is the CEG servers rejecting the request to CEG the exe. Bank check the release state on the game page. If it is not 'playable', you volition need to asking Steam keys that override the release state.

"The Steam Servers are too decorated to handle your request... Error Code (ii)" at launch time
