One plus to NO. Tried to upgrade my 32-bit XP installation with 64-bit
Ultimate disc from XP it said setup is not made for this machine, and
booting from the Upgrade disc said my key only good for Upgrade (so it
not found the 32bit installed XP). Dont wanted to mess with my 64bit XP
got by Technology Advanced Program (so not know if i would be able to
upgrade from it), so just installed Vista Ultimate without key, then
upgraded with clean install with upgrade key. (funny that Vista x64
accept itself as an upgrade base, but not the 32bit XP)
