Short version: I need a copy of the Windows Vista installation files, suitable for creating an install ISO. I have a valid product key, I just lack the files. Help?
Long version: I recent acquired a little Fujitsu Lifebook, but it's in Russian, and there don't seem to be any other languages installed, so I want to just reinstall the OS, but I don't have an install drive or set of disks for Vista. I tried Windows 7, but it seems it can't quite handle it (or at least, not the 64-bit version I have files for), so I'm stuck trying to track down Vista. The product key on the back is still legible, so I'd hate to have buy a new copy of Vista for it (forgetting the fact that I'm not sure who I'd be able to buy one *from*, in any case...), but I seem to be out of options. If anyone knows of a place I can get a legit, uncracked copy of the Windows Vista installation files, I would be very grateful. Bonus points if it's already an ISO.
