There is no upgrade path from a 32-bit version of Vista
to the 64-bit version of Vista. You'll need to purchase
a "full version" of the 64-bit version and perform a
"clean install". The 64-bit upgrade version is only valid
if you already are running a 64-bit version of Windows XP.

"Windows XP Professional x64 users can purchase an upgrade
license for the 64-bit version of Windows Vista.
However, they must perform a clean installation of the operating system."
