Debugging Runner and Launcher

On this page, you will learn how to debug and report issues with the runner and the launcher. You might want to read Launchers Lifecycle first.

Getting the logs

Runner and launcher logs are usually the first thing you should be looking into. Here’s the list of where runner and launcher logs can be found.

Watch out, since both runner and launcher logs will get overwritten as soon as you start your game again. If you want to keep them (to send them to support@patchkit.net, for example), you have to make a copy before each run.

Runner

Operating System Location Notes
Windows launcher-log.txt Next to launcher.exe
Windows %APP_DATA%/Remote/patchkit-launcher/launcher-log.txt >= 1.5.1 if WORKDIR is restricted
GNU/Linux launcher-log.txt Next to launcher binary
Mac OSX ~/Library/Application Support/PatchKit/Apps/launcher-log.txt  

Unity-based single-launcher

Operating System Location
Windows C:\Users\username\AppData\LocalLow\UpSoft\PatchKit Patcher\output_log.txt
GNU/Linux ~/.config/unity3d/UpSoft/PatchKit Patcher/Player.log
Mac OSX ~/Library/Logs/Unity/Player.log

Note that if you’re using a custom launcher and you change Company Name and Product Name in it’s setting, the path may be different. For more information, please see Unity documentation.

Electron-based single-launcher

Operating System Location  
Windows C:\Users\username\AppData\Roaming\patchkit-pathcer\secret\pk_logs\  
GNU/Linux $XDG_CONFIG_HOME/patchkit-patcher/secret/pk_logs/ If $XDG_CONFIG_HOME is set
GNU/Linux ~/.config/patchkit-patcher/secret/pk_logs/  
Mac OSX ~/Library/Application Support/patchkit-patcher/secret/pk_logs/  

Electron-based multi-launcher

Operating System Location Notes
Windows C:\Users\username\AppData\Roaming\launcher-name\pk_logs\  
GNU/Linux $XDG_CONFIG_HOME/launcher-name/pk_logs/ If $XDG_CONFIG_HOME is set
GNU/Linux ~/.config/launcher-name/pk_logs/  
Mac OSX ~/Library/Application Support/launcher-name/pk_logs/  

Command line arguments (unity-based only)

The launcher (formerly patcher) should be run with the following command-line arguments:

" patcher.exe --installdir "dir" --secret "secret" --readable

You can try and launch it with your custom installdir and secret. Remember always to pass --readable, because otherwise, the patcher will expect an encoded secret instead of a string.

Environment variables

Launcher behavior can be overridden by setting up those environment variables.

Variable Name Description
PK_PATCHER_FORCE_SECRET Set it to application secret to forcefully change what game should be downloaded.
PK_PATCHER_FORCE_VERSION Change the latest game version to the given one. This is internal version id starting from 1.
