Hi, Actually, i install my games into two differents prefix, once in the 32bits prefix and the 64bits prefix. For my test, i tried to install 3 games : - F.E.A.R - Mass Effect 1 - Runaway : A Twist Of Fate F.E.A.R : No problem with the 32bits wineprefix but impossible to install in the 64Bits Wineprefix... It's a joke because in the CD, it's write that the game works on XP 64Bits. I could write here the output message in my console. 32Bits = Install Ok, Runs Ok 64Bits = Install fails Mass Effect 1 No problem in Wineprefix 32/64bits, the game works correctly. Even if the graphic quality in 64Bits is inferior than 32Bits 32Bits = Install Ok, Runs Ok 64Bits = Install Ok, Runs Ok Runaway : A Twist Of Fate For this game, it's very very strange. With the two versions of wineprefix, the installation is complete and works completly. The problem come from when i launch the game : - When i add a CDROM drive in Winecfg, the game works completly without crack with the DVD in my DVD Drive in the 32bits wineprefix. - I did the same thing in winecfg for the 64bits wineprefix but impossible to launch the game with the DVD, i must to use a No-CD crack. The game use Securom, it seems that the bug (http://bugs.winehq.org/show_bug.cgi?id=7065 still exist for Wine64. I can make a mistake Thank you for having read my message and bringing your ideas
