title: Excel Add-in doesn't get the hint
body: <p>I have an excel add-in that keeps coming back when I start excel, even though I've removed it from the last open instance of excel (yes I checked the processes in task manager).</p>
  
  <p>The critter even shows up when I start excel in safe mode. </p>
  
  <p>Anybody else had this?</p>
