After being stuck on "RUNTIME ERROR", I try to uninstall the game e reinstall. Nothing happens. I thought some corrupted files are still there so I deleted the entire folder. Now I cannot install the game either from gog galaxy or directly due "server error" thing...

Somebody can help me?

Please contact support. It will be helpful to know if the failure is shown when the installer tries to launch the game at the end of the installation or earlier.

NVM - wrong topic ;)
