title: How can I roll-back a ClickOnce application?
body: <p>Is there a way (hacky will do) to allow a user to go back to a previous version of a <a href="http://en.wikipedia.org/wiki/ClickOnce" rel="noreferrer">ClickOnce</a> network deployed application?</p>
  
  <p>I've looked in the docs and API and there seems to be no way. You <b>can</b> selectively choose if you would like to update, but once updated there is, seemingly, no way back.</p>
