I purchased a used media center PC from someone. They had MC20 installed on it, but they removed it before selling it to me (it was a virtually clean PC software-wise when I received it). I downloaded MC21 and installed it, then recovered my MC22 Master License using my own registration code and installed it. But when I go to Help/Registration Info, it shows that MC21 is registered to the previous owner of the PC. I've tried uninstalling and reinstalling (and telling it to remove registry entries/database info during the uninstall process) and it still shows the previous owner. I figure that this information must be stored in a secret place somewhere, which I would like to delete so that I can use my own MC22 Master License and have the software show that it is registered to me.
Can anyone help with this?
