Hmm I downloaded the GOG installer just in case of ( Don't ask where, I'll remove it after tests). And tried the GOG script, which was waaay too long to do (I don't got a good internet connection to be honest).
So i just installed the game the classic way via lutris ("Add game"-> "Runner=wine"->"Game option=path to installer"->Install the game-> Once installed, right click on the game on the lutris list then "configure", and in game option change the path to the installer to the path for the installed .exe) and it just worked :S, so I don't know what to say to you.
Just in order to be sure, open a terminal and put this command :
sudo eopkg install wine wine-devel wine-32bit-devel winetricks
With a bit of luck it's just a program that you forgot to install 🙂
