Maybe I have overlooked this in the docu, but I'd like to know if there is a command line option to set the windows version, like eg. wine --version=98 "c:\\foo\\bar\\spam.exe" wine --version=xp "d:\\honk.exe" I am asking because I have quite a lot of windows software (ie., games) that has buggy installers and/or core engines, and switching the wine default version *every* time until I have installed them all and have set the versions to use would be a bit tedious.
