I just noticed that, when testing Lexware[1] with wine, that winetricks does not seem to reset the windows version correctly (or at least the Service Pack Number).
On a fresh wine-installation I executed:
winetricks msxml3 jet40 mdac28 dotnet20
When I now start the Lexware-Installer it says that "SP4" is installed (so it seems to be the setting for Windows 2000), but winecfg shows "Windows XP".
When I run
winetricks winxp
afterwards, the installer correctly displays "SP2".
Tested winetricks 20090227 with wine 1.1.16
