Launcher configuration

The launcher config file is located in your game directory under launcher/config.json. To edit it you have to open the file with a text editor (notepad, notepad++, vs code..).

  • Directoryiw4x/
  • Directorylauncher
    • config.json
  • Directorymain/
  • iw4x.exe
  • ..

The config is a JSON file, if you are unsure you can use a JSON Formatter to make sure its valid before running the launcher.
