Hi, There is a problem with this game since more wine version. If you play at this game with the vanilla version or if the patch 1.01 is installed, the game runs correctly without problem. But, if you installed the patch 1.02 or patch 1.03, impossible to launch the game, wine crash quickly. Error message : Code: berillions@Debian64:~/.wine/drive_c/Program Files/Ubisoft/Assassin's Creed Brotherhood$ wine ACBSP.exe wine: Unhandled exception 0xc0000417 at address 0x1d24793 (thread 0009), starting debugger...

No process loaded, cannot execute 'detach' It seems that the problem come from with the patch 1.02 because if i replace the 1.03 executable by the 1.01 executable, the game runs. The patc 1.02 fix these problems : Code: Single + Multiplayer * Fixes an issue that prevents player settings and game progress from being saved if the user?s Windows login name contains unicode characters. * Fixes an issue where users could not add friends whose names contain dot characters. Multiplayer * Changed network communication port from 1000 to 7917 in order to fix connection issues caused by some ISPs? restrictions. So when i launch the game with winedbg, i have this message : Code: berillions@Debian64:~/.wine/drive_c/Program Files/Ubisoft/Assassin's Creed Brotherhood$ wine winedbg ACBSP.exe WineDbg starting on pid 0020 start_process () at /home/berillions/Desktop/wine-1.3.27/dlls/kernel32/process.c:1087 0x7b85d66f start_process+0x4f [/home/berillions/Desktop/wine-1.3.27/dlls/kernel32/process.c:1087] in kernel32: movl %edi,0x4(%esp) 1087 return call_process_entry( peb, entry ); After these try, i don't know where search to find where come from the problem (and if it's possible to resolv it) PS : The game install Punkbuster but it launched with Brotherhood 1.0 / 1.01 and the game works. Thanks
