title: NSIS Installer with .NET 4.5
body: <p>I'm after some code snippets for NSIS to detect and conditionally run the .NET 4.5 installer</p>
  
  <p>This answer - <a href="https://stackoverflow.com/questions/3542496/nsis-installer-with-net-4-0">NSIS Installer with .NET 4.0</a> - is too naive as checking only the presense of the registry key (not the value) will not discriminate between 4.0 and 4.5</p>
