I was having problems with the .net framework, whenever I open a .net application it just crashes, and Microsoft Visual Studio 2008 isn't working too well either. I ran the windows 7 .net framework uninstallation tool, and it said all versions are successfully removed, and now i'm trying to reinstall it, but it's telling me to use the 'turn windows feature on or off' to configure the .net framework. I tried doing that, but the .Net framework wasn't there. I tried opening the installer again, and it says i have to use the 'turn windows features on or off'. Please help?
