Hi scarpenter002,
Sorry I missed this question in your original thread.
To answer your question, I don't know. Install isn't my main area of focus, so I haven't had the chance to attempte to install Win7 (using the Upgrade process) on a non-genuine Vista.
I recommend asking that question in the 'Install Upgrade & Activate' section of the Windows 7 Answers Forum
http://social.answers.microsoft.com/Forums/en-US/category/windows7.
Any answer I gave would either be a flat guess or just a repeat of the standard corparate "that's not a supported upgrade path" line.
Sorry I couldn't be more help,
Darin MS
