Windows 7: Upgrade vs WOW for Win 7 Home Prem to Prof

Upgrade vs WOW for Win 7 Home Prem to Prof

I didn't explain my situation very well yesterday so let me try again.

I have a new laptop that came with Windows 7 Home Premium. I bought Windows 7 Professional Upgrade from download along with the backup disc. Unfortunately, the Windows 7 Professional Upgrade I purchased is not the Anytime Upgrade and it can't be returned since it was obtained through the student program. Do I have a "qualifying previous version of Windows" to just do the upgrade or do I need to reformat this hard drive and install my upgrade version from boot (clean or custom install)?? If a clean install is necessary, how is hard drive reformat accomplished? Please point me to the appropriate installation instructions for this scenario. Need and appreciate help Thanks a bunch.

No install files needed.
Only the Upgrade key is need.
Anytime upgrade only adds-on the Programs & Features from version to version.

Same answer as yesterday. Insert the Professional key in Anytime Upgrade. MS wouldn't make it possible if it didnt' qualify to upgrade with the Upgrade or full version key, not just Anytime key.
