i received 2 copies of Windows Vista Business being a part of the MSDN alliance as a part of my major in my college. One of the keys came with a 32-bit iso download and one of the keys came with a 64-bit iso download, but both of my machines i'm running that i'm installing vista are 32-bit. Should the key that came with the 64 bit version install with the 32-bit install DVD, or is that key specifically for the 64-bit business version?
I'd like to know if it's possible before i back-up my entire other system to reinstall windows, and end up having to reinstall XP again and waste a few days in the process...
