Hi guys, im currently having problems getting .Net to activate in the "Turn Windows Features On/Off" section of the control panel. As others have stated here before the box is filled, not checked. when i click on the plus button to expand the options both Windows Communication Activations options are unchecked. when i check them and select ok, windows tries to activate but then i get an error that says "An error has occured. Not all features was successfully changed" and then it asks me if i want to restart now or later. when i check to see if the commands were completed, im right back at square one with .Net on the windows features list being unchecked and thats whether i perform the restart or not. I know that others here have had the same problem and i was wondering what i can do to resolve the issue. Also when i check to see if updated are available it does say that .Net 4 is available but when i try to update the update program never completes the installation.
