title: Update VSTO Word Addin without VSTO auto-update (no rights for installation for users)
body: <p>I want to update a VSTO addin for word I create without let VSTO automatic update launch. In fact, my end-users have not enough rights for installing.</p>
  
  <p>I only want to update it, not install because first install will be done with vsto installation from VS publish folder with administrator rights.</p>
  
  <p>To update, I copy </p>
  
  <pre><code>MyWordAddIn.dll  
  MyWordAddin.dll.manifest
  </code></pre>
  
  <p>from publish folder to appData folder where my addin is installed.</p>
  
  <p>When I launch my word document which is linked with my VSTO file. I have an error </p>
