I've got a legit Windows Vista Ultimate x64, which I bought from amazon or somewhere like that. The DVD says "This disc contains 32-bit software only" on it. Is it possible to use my product key with x64? And where can I get it? I assume I can't just download an MSDN version or whatever...?
Where you get it, is really up to you... yes MSDN will work as any The key works on 32 or 64 bit version sebus
have my doubts... I have bought 2 vista ultimate editions; both came with a 32 and a 64 bit DVD and each had their own key, and I do recall reinstalling my 32 bit version, whence I began to type in the [wrong] 64 bit key; and the installer would not accept the key. So I doubt that a 64 bit key will activate a 32bit version
