title: clickonce auto update issue
body: <p>I have an excel vsto add-in. I am distributing this add-in by sharing the clickonce installer file. Later, I tried to make this application auto update. for auto updating my application, I created a c# console application, which</p>
  
  <ul>
  <li>downloads the latest clickonce installer</li>
  <li>closes the excel</li>
  <li>uninstalls previous version of addin</li>
  <li>opens the clickonce installer</li>
  </ul>
  
  <p>the first 3 steps are working fine. </p>
  
  <p>for the fourth step I used <code>Porcess.start('file_location to clickonce setup.exe)</code></p>
  
  <p>if the user account is admin, there would be no problem, otherwise it would ask for admin password, if the admin password is given, the addin gets installed in the admin account and not in the user account. </p>
  
  <p>I am struggling to actually understand how to auto update vsto addins if clickonce is used and distributed manually.</p>
