Visual Studio 2013 installation error: .NET 4.5 needs to be enabled, but already is

I have a problem with Visual Studio Ultimate 2013. When I started the installation process, I got an error related to the .NET Framework 4.5.1, 0x800713ec Asia. I try to install .NET Framework 4.5.1 and I downloaded it from microsoft.com, but I have got the next issues:

Blocking Issues:

The .NET Framework 4.5 and this update are already installed on your computer as part of the Windows operating system, but they must be enabled. In Control Panel, choose Programs and Features, choose Turn Windows features on or off, and then select the .NET Framework 4.5 check box.

Setup cannot continue because a previous installation requires your computer to be restarted. Please restart your computer and rerun Setup.

I did this recommendation, but nothing happened.

Just go to settings --> power --> and then update and restart . and then again Run Setup
