title: Stopping display of custom dialog boxes in WiX uninstall
body: <p>I have a WiX installer project that utilises a custom dialog box to ask for parameters to update a web.config file and run a database script on install.  Everything works correctly and the application is installed and runs correctly.</p>
  
  <p>However, the custom dialog box is also displayed when I uninstall the software and it certainly doesn't need to be (as I'm not updating a web.config file).  </p>
  
  <p>Is there a way to suppress the custom dialog when the application is being uninstalled?  </p>
  
  <p>(I should also remove the sql procs I install, at uninstall time but that is outside of this issue).</p>
