I purchased a device for scanning slides to my PC, which at the time was (and still is a desktop running XP). I later bought a more powerful laptop running Windows 7, and looked forward to using the scanner on the newer and faster machine. But no, I couldn't because there was no driver available for the scanner in Windows 7. Result, I either have to stick with using the older desktop or junk the scanner and buy a newer one.
Errrrr no, I have the same problem with a film scanner, I just run it in a virtual m/c running XP (free from Microsoft) within windows 7, problem solved. You do need windows 7 pro though.
