Thanks for the help. The issue is resolved. I found out that I didn't have enough disk space to reinstall it, so I deleted some things and reinstalled the staging file.

Yes I have. It doesn't work. I can't find the product code in Regedit

I have gotten this error a few days ago and now I can't open Paint.net. I can't seem to uninstall Paint.net either because it doesn't appear in the Uninstall list. I've tried windows troubleshooter but I cannot locate the product code. The only thing I can think to do right now is revert my system to a previous date but that is too much to ask right now for this problem.
