I know what happened, not entirely sure why it won't install from this or how to fix it though Being my stupid self, i accidentally deleted the Paint.Net folder in my Program files instead of the one I wanted too. I tried to just reinstall, but it gives me a 1603 fatal error, anyone have any ideas how to fix this? Just to mention this, incase it matters. I followed the one sticky, and it didn't help at all. nvm, problem solved. For anyone that might also have this issue, just use Windows Installer Clean Up Utility. Works like a charm.
