Step 1. Open your Control Panel, change the View by type to Large icons, and select Programs and Features.

Step 2. Click on Turn Windows features on or off from the left pane.

Step 3. In the Windows Features window, see if the .NET Framework 3.5 (includes .NET 2.0 and 3.0) is enabled. If not, you can tick the checkbox and click on OK to download and install NET 3.5. After that, the NET 3.0 and 2.0 should have been installed too.
