Windows 7: Win 7 Home Upgrade Help

Hi,

I have Win 7 Home premium X64 installed.

I have just purchased Microsoft Windows 7 Professional 64-bit Upgrade Edition

When trying to add my new key to the anytime upgrade, it says that the key is not valid, although I was assured that this would work.

Do I need to get a refund? Can I use the DVD to do an in place upgrade?

Upgrade Edition is different than what WAU is expecting. This key is for use for installing over Vista. You should be able to do n in-place install, but the proper key would be cheaper I think.

You should be able to use an Upgrade or Full retail key in Anytime Upgrade. Try rebooting.

If not there is a workaround to in-place Upgrade between Windows 7 versions by tricking the Home Premium installer into thinking it is doing the always-allowed same version Repair Install.

First save a Windows 7 backup image so you have a path back to your current version: Backup Complete Computer - Create an Image Backup and back up your files.

Next set a System Restore Point - Create, type Regedit in the Start Search box, rightclick result to Run as Admin, carefully change the two registry keys shown below to HOMEPREMIUM for the EditionID, and Windows 7 HOMEPREMIUM for the ProductName. Then run the installer from desktop, activate with new key:
