Sorry I'm a newb, but what is a 'clean prefix'?
A clean prefix is one where nothing has been installed or run under. The default wine prefix is ~/.wine, you can set the active prefix using an environment variable by running the installer like so:
cd /media/cdrom WINEPREFIX=/home/daniel/wine-bf1942 ~/git/wine setup.exe
