Hello,
Sorry to hear you are having trouble.
Keeps asking me for my product key and i put it in and it says it activated but then it just keeps asking for it.
Press the Windows key and "R" at the same time. A "Run" dialog box will pop up, please paste the path below into the "Open" field and press OK.
%ProgramData%\Stardock\
In the folder that pops up, you should see a folder named DeskScapes. Please delete this folder and all of its contents.
After you have deleted that folder, please attempt to activate once again and it should succeed without any errors.
