you try run as administrator? you download the game from gog or gog galaxy? i tell you my story with the game, gog galaxy is not compatible with the game right now but you can download the installer in "download extras", i download it from here and the game runs fine, hope i help you bro
alright thank you it seems to have worked
When I want to install the game is says not compatible,but in description is said its compatible with Windows 7
The game is currently not compatible with the Galaxy client. You'll have to install it without the client.
Are there any issues with the game that I should be aware of?
