Okay, before someone complains I wasn't reading the other posts to figure this out, just saying, I did. For the last four days. And they even locked the thread, so I couldn't get help (so I created this =D).
Basically, at one point in life, I pretty much manually deleted paint.net from my computer. When I tried to re-install it, it gave me this error. When I then installed an earlier version, it claimed it couldn't install because a later version was already installed.
So far, I managed to clear everything about Paint.net there was. But.. since I pretty much give up at this moment, if anyone has paint.net INSTALLED on their computer, I would appreciate it if someone would upload the data files on... (mediafire? Something?) so I can download and use paint.net without installing it?
It would be appreciated! Thank you in advance~
