I have a Windows XP Service Pack 3 computer with .net Framework 1.1. When I try to download Paint.net version 3.5.6, it gives error message. As I understand it, version 3.5.6 asks for .net Framework 3.5. The problem is that .net Framework 3.5 is incompatible with net Framework 1.1. This means that I would have to do all kinds of maneuvering to get it to work and I am not that savvy or that comfortable digging into things. I understand that .net Framework 4 is compatible with .net Framework 1.1. Any chance you can allow .net Framework 4?
