Repairing corrupted game files can help resolve issues such as crashes, graphical glitches, patching errors, or problems launching the game. Here's how to repair game files:
GOG:
- Launch GOG GALAXY and log in with your GOG.com account.
- Choose the game from Owned games tab.
- Click Customize button (to the right of Play button) → Manage installation → Verify/Repair.
- Wait for a few minutes until GOG GALAXY verifies the files.
Steam:
- From the Library section, right-click on the game and select Properties from the menu.
- Select the Installed files tab and click the Verify integrity of game files... button.
- Steam will verify the game's files - this process may take several minutes.
