ok... now i have to ask stoopid and hard questions

is it possible to upgrade from x86 vista ultimate to x64 w7 ultimate?

my hardware does support x64 software

and if its NOT possible.. plz tell me why
From what I understand a 32 bit OS can't be upgraded to 64 bit. You would have to do a fresh install. By the very nature of how the OS is put together won't allow x86 to become x64. If you want x64, you'll need to start fresh.
