title: Powershell 5.1 in Windows 2012 R2
body: <p>I would like to install/upgrade powershell in my Windows 2012 R2 server.
  As default w2k12 have 4.0 powershell so I've downloaded Windows Management Framework 5.1 as file: W2K12-KB3191565-x64.msu
  When I run this - I'm getting error "The update is not applicable to your computer" - ok... researching google FOUND ... </p>
  
  <p>I have to install full version of .NET Framework 4.5.2 - so ok.. Downloading dotNetFx45_Full_setup.exe and RUN.</p>
  
  <blockquote>
    <p>Error: ""Microsoft .NET Framework 4.5 is already a part of this
    operating system.  You do not need to install the .NET Framework 4.5
    redistributable. Same or higher version of .NET Framework 4.5 has
    already been installed on this computer.:"</p>
  </blockquote>
  
  <p>OK trying install Developer Version NDP452-KB2901951-x86-x64-DevPack.exe</p>
