Windows 10 Error code: 0xC004C003

[Tori77904]

So I downloaded the Windows 10 FREE update and now have a box in the lower right corner saying Activate Windows, go to settings. I followed the instructions and the computer gave me Error code: 0xC004C003. Saying that my product does not work for Windows 10.

Please help me resolve this issue.

Do I need to uninstall and go back to Windows 8 Home and do something there?

Do I HAVE to purchase a new product key?

HELP PLEASE!
