I wanted to install WBFS Manager by AlexDP which requires .net framework 3.5. So I ran the setup for that which failed midway saying it encountered a problem. I searched for fixes and got pointed towards the .net framework cleanup utility to remove previous versions of .net framework. So I ran that, it cleaned up successfully, but the 3.5 setup still gives the same error. Stupid Microsoft. Can somebody help? I'm on Win XP.
