Detailed analysis

GOG Galaxy crashing or failing to launch games is usually fixable without losing your game saves or installations.

How to fix it:

  1. Verify game files: GOG Galaxy > your game > Manage Installation > Verify / Repair
  2. Try launching the game directly: navigate to the game's installation folder and run the .exe directly, bypassing GOG Galaxy
  3. Clear GOG Galaxy cache: delete %LOCALAPPDATA%\GOG.com\Galaxy\webcache and %PROGRAMDATA%\GOG.com\Galaxy\webcache
  4. Install all Visual C++ Redistributables (2005-2022, x86 + x64) and DirectX End-User Runtime
  5. Add the game folder and GOG Galaxy to your antivirus exclusions
  6. If GOG Galaxy itself crashes, rename %LOCALAPPDATA%\GOG.com\Galaxy\Configuration\ to force a fresh config
  7. Reinstall GOG Galaxy without uninstalling games — the new install will detect existing game folders
  8. Run the game as Administrator if it still won't launch
