I have this problem where I can't launch the game through the EoCapp EXE file. I can launch the game just fine through the conventional Larian client. But when I try to launch the game through the EoCapp file, the screen goes black as if to launch, and then it automatically closes down. So far, I have tried to verify the game files, run as administrator and let it pass through the firewall. None of these efforts have been successful. Not sure if it's relevant but I got the game from GOG

Anyway, would be grateful for any help
