title: WIX - auto update
body: <p>I have a standalone setup project created with Wix. And I need some solution for auto-update my application. My application should check for a new version on startup and automatically download and install the new version if available.</p>
  
  <p>What's the best solution to do this? Is there something like ClickOnce in Wix? ClickThrough seems to be dead, am I right?</p>
