Some programs need the .net 1.1 to work. It's a web service developed by Microsoft for Windows to enable you to use your application software any time, any place, on any device. Web services cannot work without the .Net Framework. To me, 2.0 is like Windows SP2. You don't really need Framework 2.0 to run. Just leave the 1.1 there. If that solves the problem, then it's fixed. If not, then I have no clue.
