If you're mounting from an ISO (which I *think* is required with Sims 3 on Wine), try Code: sudo mkdir /media/iso sudo mount -o loop ISOFILE.iso /media/iso then Code: mount /media/iso/; env WINEPREFIX=~/.wine wine /media/iso/PROGRAM.exe You can use another prefix in this last command, if you want to put it into a separate "bottle".
