Re: Vista 64bit from 32bit install question
It is the product key, not the disk, which determines the version of
Vista installed and is used for activation. All 32-bit and 64-bit disks
are the same, whatever labels they carry, so there are only 4 Vista
installation disks - 32 and 64 bit RTM, and 32 and 64 bit SP1.
You can safely use the 64-bit disk you have with your second product key.
Any Vista installation disk can be used, without a product key, to
install a 30-day trial of any version of Vista. 32-bit disks can only
install 32-bit Vista and 64-bit disks only 64-bit Vista.
