If her copy of Pro Tools is a version tied to hardware (like the M-Powered versions) then no, it will not work in any 64-bit Windows. It has to do with the way Digidesign programmed their hardware communication (ie, very poorly); it seems they're "working" on it, but I wouldn't hold my breath. I'm pretty sure the dongled versions of other [now] Avid software has the same issue. (All my Pro Tools and various Avid video editor experience is with Macs, and even there certain versions will outright refuse to run on certain OS revisions.)Otherwise, baring bad programming practices, anything that runs on Windows 7 32-bit will run on Windows 7 64-bit via WOW64; unless the program goes out of it's way, it can't even tell it's not running on a regular 32-bit OS.
