Rather long story, but I'll try to be as brief as possible...
I recently had to reset my computer due to technical issues, and I'm having a world of trouble getting paint.net back. I don't remember any trouble installing it when I first got this computer (around two years ago), but now, the download refuses to finish. Apparently it's because I need .NET framework 4.6, but when I download that, it simply won't open, and paint.net remains stuck. Trying a different version of the .NET framework doesn't seem to do anything, either.
This is probably a strictly amateur problem, but I'd really appreciate any advice.
