I have a new PC running Windows 7. It is a 64bit AMD HP with quad core processor.
I installed visual studio 2008 and visual studio 2008 SP1. I'm trying to install WPF toolkit but when i try to install it it gives me a message to install .net framework 3.5 SP1.
When i try to install .net framework 3.5 SP1 i get a message that says i need to "Turn Windows features on or off"
So i go in control panel and Programs and then in the Turn Windows features on or off menu i check the checkbox under Microsoft .NET Framework 3.5.1 as shown in the image attached.
I'm still getting the message that says "turn windows windows on or off" even after I check all the boxes as shown in the image.
Can anyone help on why I can't install .net framework 3.5 sp1?
