The license for the version of XP that is used as the basis for the upgrade
to Vista is subsumed into the Vista license, so it is against the Vista
license agreement for the underlying XP to be installed at the same time.
You can use the same product key to install x64 Vista, but first the x86
version has to be removed. There is no deactivation.
