title: How to install redistributable package of .NET Framework with Wix?
body: <p>I have a general task: install .NET Framework 3.5 during the setup of my product.</p>
  
  <p>I do the following:</p>
  
  <ol>
  <li>I have created a custom action X</li>
  <li>Custom action X starts an executable Y via Process.Start()</li>
  <li>Executable Y kills the msiexec process and run .NET Framework setup package</li>
  </ol>
  
  <p>Here appear some problems: .NET Framework setup says that Windows Installer Service is not accessible and asks to terminate all another installations!</p>
  
  <p>I think, the cause of it is that Process.Kill() method terminate the process incorrect. When I kill the msiexec process via Kill() the <strong>msiserver</strong> service is NOT STOPPABLE, but if I finish setup by clicking Cancel button, <strong>msiserver</strong> service becomes STOPPABLE.</p>
  
  <p>How can I solve the problem?</p>
