Upgrade from windows 7 home premium to professional from disc

Hi guys,

I currently have windows 7 home premium 64 bit edition on my desktop. I get a copy of windows 7 professional 64 bit disc with legal key from my university for a student special. How can I upgrade? I was redirected to windows anytime upgrade during the installation. But my windows 7 professional x64 product key was not accepted there. I already have lots applications installed so I don't want to do a clean install. Any suggestion? Thanks!

Your original installation may have an "OEM" license and your pro license may be retail.

Yes, I have different keys on these two versions. So I can't upgrade from home premium to professional using the disc?
