This is considered a full-version of Vista 64-bit. As this is an OEM version, Microsoft will not be providing tech support. These OEM editions are meant to be installed on PC's with no OS, but you may use them as an upgrade if you wish. All versions of Vista are available in both 32 and 64-bit versions. With OEM packs, as there is only one DVD, you have to select which one you want before proceeding to checkout. If you're using an upgrade copy, only Ultimate has 64-bit in the same packaging with a 32-bit edition. With all other versions of Upgrade, you will need to contact Microsoft to get 64-bit. The full retail edition of Vista includes, in all versions except Starter which isn't available in the U.S., EU, or most other industrialized countries, both 32 and 64 in the packaging.
