title: VSTO Excel Add-in Won't Load
body: <p>I'm currently working on a VSTO Excel add-in project. The add-in was successfully installed by our users. The problem is, only the admin users can view the add-in, non-admin users can't seem to load the add-in, loadbehavior always sets to 2. The non-admin users can't also set the VSTO system environment to enable logging. </p>
  
  <p>Am I missing a step in the installation process?
  Is there a workaround for this?</p>
  
  <p>Any help would be greatly appreciated, thanks.</p>
