Installing Paint.Net on Windows 7

The latest and greatest version of Paint.Net (v3.5.1) has been released and is awesome. If your running Windows 7 you may come across an issue when you install it namely it thinks .NET 3.5 SP1 isn’t installed and quickly bumps you off to the download from Microsoft. This is a tad annoying as Windows 7 comes preinstalled with this edition of .NET.
