Windows 7: Cannot perform upgrade from win 7 Home Prem to Win 7 Pro

Cannot perform upgrade from win 7 Home Prem to Win 7 Pro

Issue is on my laptop which is an HP. It is currently running Windows 7 Home Premium x64 HP OEM. I have a valid copy of Windows 7 Professional x64 but whenever I try doing an upgrade it tells me to use Anytime Upgrade, which will not work with my serial key.

I would rather not do a full install if possible, and am curious why I cannot perform this upgrade?

Any comments or suggestions would be helpful.

BTW My Win 7 Pro license is an MSDN AA key from my school, never activated and legit.

Your spec's show that you have three OS's already installed.

the only 'upgrade' option you have is ultimate...for all others, must be clean install...

Are you typing in right key No.

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

If Anytime will proceed with upgrade HP>Pro then it should accept a retail key. Try again.

If not, there is a workaround to change between versions of Windows 7 using an in-place Upgrade from disk. Question on updating from home premium to pro

Which worked: inserting retail key in Anytime, or doing the reg workaround to change versions in-place via Repair Install?
