What can I reinstall/upgrade Vista Ultimate OEM 32 bit Vista Ultimate 64-bit using the upgrade CD that I bought?

Please help me with the steps I must follow to upgrade/reinstall my Vista Ultimate OEM 32 bit Vista Ultimate 64-bit.  I bought the upgrade CD, but I keep reading that I can't upgrade, I have to re - install.  How do, or have I just wasted my money?

Thank you

David

The two DVD come in the box of Vista Ultimate.  The same upgrade key works for both.  The procedure is to let the 32-bit version on the hard drive for the verification of license and a custom installation will work.  The hardware hash will be the same and the product key is the same for the activation servers to happen anyway as a repair installation.
