I upgraded from Vista Ultimate to Windows 7 Home Premium last year (download w/ backup DVD). My hard drive crashed a month ago and without thinking, I did a clean install of Windows 7 on the new hard drive. Of course it wouldnt let me activate it since
my product key is for upgrade only. So I reinstalled Vista and tried to use my Windows 7 install disc to upgrade. I keep getting a message that says I cant upgrade from Vista Ultimate to 7 Home premium and it wants me to do a clean install. If I do this, Im
affraid it wont take my product key again. What should I do???

Right click CMD, click ‘Run as administrator’
At the command prompt, type, regedit
Go to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersionsetup/OOBE/mediabootinstall
changed its value to 0
Go back to the Command Prompt, type the following:
Restart the pc and use the activate windows to re-enter your product key
Then use phone activation to activate the software:
