title: How to execute custom action only in install (not uninstall)
body: <p>I'm sure this is fairly easy, but I've kind of had a hard time with it. I've got a custom action that executes a different (non-msi) installer on installation. Unfortunately, I've noticed that it also executes the installer on UNinstallation!</p>
  
  <p>I've looked through the options but I cant' seem to find out how to stop this. If anybody could help me I would be incredibly grateful.</p>
  
  <p>Also, how do I set a custom action to go off only during UNinstall? Any help is greatly appreciated guys!</p>
