Sorry, guys, but when I see wrong info I think it has to be corrected.
If you have Windows Vista 32-bit, you most certainly can buy and use Windows 7 64-bit Upgrade. You can not do an upgrade installation, only the clean one. Windows 7 x64 Upgrade disk needs only to verify you are eligible to use an upgrade option. It does this by checking that your Vista x32 is authentic and licensed.
After checking your systems eligibility, install continues normally but the upgrade option is grayed out, leaving you only the option to do a clean install.

Thank you, Kari, for posting 100% accurate information. With MS provided installation media for all MS OS's ever sold, you do not purchase the OS. You purchase the license.
An upgrade disk contains the entire OS. It is not a patch or service pack. The user will be prompted to insert the qualifying OS media, or to provide a valid license key for the qualifying software.
