title: Popping up a dialog/message after NSIS install in silent mode
body: <p>I have an NSIS installer set to run in silent mode. This works very well.</p>
  
  <p>I've had a customer request for an informational pop up once the install has complete...but still wants the installer portion to be silent! </p>
  
  <p>I realize this is counter intuitive. </p>
  
  <p><strong>That being said is there away to override the silent at the end of the install?</strong> </p>
  
  <p>I currently set the installer attribute below at the beginning of the .nsi script</p>
  
  <pre><code>SilentInstall silent
  </code></pre>
