title: Windows SDK 7.1 Setup failure
body: <p>I am trying to install Windows SDK for Windows 7 with .NET Framework 4 but when I open the setup I receive an error:</p>
  
  <blockquote>
    <p>Some Windows SDK components require the RTM .NET Framework 4. Setup
    detected a pre-release version of .NET Framework 4. If you continue
    with Setup, these components will not be installed. If you want to
    install these components, click Cancel, then install the .NET
    Framework 4 from <a href="https://go.microsoft.com/fwlink/?LinkID=187668">https://go.microsoft.com/fwlink/?LinkID=187668</a> and
    then rerun Setup.</p>
    
    <p>Click OK to continue.</p>
  </blockquote>
  
  <p>When I went to install the .NET Framework 4 it appears a message saying that there is already the .NET Framework 4 on my PC:</p>
  
  <blockquote>
    <p>The Microsoft .NET Framework 4 is already part of the operating
    system. No need to install the .NET Framework 4 redistributable. <a href="http://go.microsoft.com/fwlink/?LinkId=164207">More
    information</a>.</p>
    
    <p>An equal or higher version of the .NET Framework 4 has already been
    installed on the computer.</p>
  </blockquote>
  
  <p>I don't know what to do anymore. I am using Windows 10 Enterprise (x64).</p>
