4) Please go to the game installation folder:
- If the game was installed via GALAXY, please select the game in GALAXY, click on the icon on the right side of the PLAY button -> Manage Installation -> Show Folder
- If the game was installed via offline installer, then you will have to manually navigate to the game installation folder, by default it's: C:\GOG Games\game-title\
Once in there find game's executable, right-click on it, and select Properties. In the properties window please switch to the Compatibility tab, and enable "Disable full screen optimization" and "Run as administrator". Press Ok to apply settings, and try to run the game again using the executable file.
