Graham, Yes it can be done. I have it installed on a Dell laptop with Win 7 32-bit only. I also have it on a Mac Book Pro with Windows 7 installed via bootcamp. Works just fine.

The disadvantage is that many newer Win 7 computers are sold with 4 gig of RAM. You need 64 bit Win 7 for the computer to recognize all 4 gigs. My understanding ( I have not tried to)is you can use XP compatibility mode to run Music Pad Manager. There is a caveat you have to have a processor that supports compatibility mode( not all processors do)also as I recall you need at least Windows 7 Pro or Ultimate version.

Freehand's future isn't looking so good. I haven't quite found an app I'm entirely happy with for displaying lead sheets with the ipad either.
