How do I install .NET Framework 3.5 on Windows 7?

Question

I need to install version 3.5 of the .NET Framework in Windows 7, but when I try to install it, it shows the following error:

"Turn on/off .NET Framework" option in System Features

I tried doing this, but I don't understand what it means. Can anyone help me?

Answer 1

Windows 7 ships with .NET 3.5 (give or take a service pack). You already have it installed.

Answer 2

That message is trying to tell you that you need to install .NET 3.5 a different way under Windows 7. Because it's included as part of the operating system, you use the "Turn Windows features on or off" function to get to it, instead of installing a downloaded redistributable package.

1. Open the Start menu and click "Control Panel".
2. Under the "Programs" category, click the "Turn Windows features on or off" link text.
