Installing Windows 7 upgrade version on a clean disk

I just finished a clean install of windows 7 with an upgrade disk. When I enter the upgrade key, it complains that the key is not meant for clean installs.

What are my options?

I have a valid vista key. Is there any way I can deal with this without reinstalling the os?

You may be able to validate the install over the phone. This is what I did after trying a variety of other alleged solutions and it worked so well I regretted not trying it earlier.
