The licensing is interchangeable, Windows Vista Ultimate retail comes with
both platforms 32 and 64 bit, but you get 1 product key. You can use product
key with either, but only with one product at a time. You cannot downgrade
from 64 bit to 32 bit, clean install only. Its most likely you will also
have to reactivate by telephone.
