My Paint.net all of a sudden had stopped working, and after an uninstall - which left the effects and shapes folder in the paint.net directory - I can not reinstall it. The installer opens, latest version (4.1.5), shows a bar saying "Extract: PaintDotNet_x86.msi...(insert percentage), where by 5 seconds later the install wizard flashes for less than a second and disappears. I went through the installation forums on this site, and downloaded the latest .NET Framework, and It tells me a version higher than that. To confirm, I have the latest ( 4.7.2). I also had recently installed the latest Nvidia Driver and re-installed the latest directx, subsequently leading to Paint.NET not opening. This is really causing me Paint.NET.
