--- Comment #12 from andy andy86@fastwebnet.it --- Hello. No. I've buy and download game from steam. Not copy from windows partition. I no more have windows installed.
Probably steam not run game setup, but just download single file and update system registry.
Steam game need to run in same wineprefix when is run steam (for me, is correct?).
