  <p><strong>Prerequisite Steps Performed</strong></p>
  
  <p>Taking checkpoints along the way :-</p>
  
  <ol>
  <li>Installed Windows Server 2016</li>
  <li>Installed IIS with .net 3.5 and CGI</li>
  <li>Installed Web Platform Installer 5.0</li>
  <li>Applied latest windows updates</li>

  </ol>
  
  <p><strong>Additional</strong></p>
  
  <p>I have been trying to locate installation binaries .msi or .exe for PHP Manager 1.2 (x64). I found an x32 version but cannot install this on a x64 OS.</p>
  
  <p>Almost every link for PHP Manager points to </p>
  
  <p><a href="http://phpmanager.codeplex.com/releases/" rel="noreferrer">http://phpmanager.codeplex.com/releases/</a> </p>
  
  <p>but all traffic appears to end up here</p>
  
  <p><a href="https://archive.codeplex.com/?p=phpmanager" rel="noreferrer">https://archive.codeplex.com/?p=phpmanager</a></p>
  
  <p>If anyone has any ideas please let me know!</p>
