title: WiX Bootstrapper run executable on exit
body: <p>I'm using the WiX (3.6) Burn bootstrapper to bundle a prerequisite component (Bonjour) with the setup for my program.  It works great and all, but:</p>
  
  <p>I'd like to add a step to the end where I run an executable from my INSTALLDIR on exit.  I'm having a bit of a hard time figuring this out.</p>
  
  <p>I've tried:</p>
  
  <pre><code>&lt;CustomAction Id="LaunchApp"  Directory="INSTALLDIR"
                ExeCommand="[INSTALLDIR]my app name.exe"/&gt;
  </code></pre>
  
  <p>But don't know where to put it in my Burn's bundle wxs file.  Any pointers?  Thanks!</p>
  
  <p>Edit:</p>
  
  <p>I've also tried putting the following:</p>
  
  <pre><code>&lt;CustomAction Id="LaunchApp"  Directory="INSTALLDIR"
                ExeCommand="[INSTALLDIR]Any Send.exe"/&gt;
  </code></pre>
  
  <p>at the end of my app's installer MSI, but when it gets integrated into the Burn bootstrapper install, this line doesn't appear to be executed.</p>
