"I just fixed it, it suddenly works. What I did is completely remove the all .net frameworks. Be sure to uninstall the higher version first. \nAfter that install again the .net frameworks, open the setup, and suddenly it started working. \nI find it weird why other programs already worked fine but only paint.net not working. \nAnyway it's already working now. I think you need to update the guide, rather than repairing (what I also did before). Completely remove all the .net frameworks and reinstall them fixed the problem. "
