Once done go to Control Panel then choose Programs and Features and then click on Turn Windows features on or off. Clear the check box for Microsoft .NET Framework 3.5.1 and then click on OK. After Windows disables the feature you will need to go back to re-enable Microsoft .NET Framework 3.5.1
This procedure can take some time to deactivate and activate .NET 3.5.1 and once done reinstall .NET 4 after downloading it from following link:

If you are uisng Windows 8:

Go to Control Panel > Programs and Features > Turn Windows features on or off
Clear the check box for Microsoft .NET Framework 3.5.1 and then click on OK. Clear also the check box for Microsoft .NET Framework 4.5 and then click on OK.
After Windows disables the feature you will need to go back to re-enable Microsoft .NET Framework 3.5.1 and 4.5 and then click ok.

Please keep me updated.
