title: If exists Add-in then Unistall
body: <p>I want the VBA code which can check if the add-in exists in the list of add-ins</p>
  
  <p>Something like</p>
  
  <pre><code>If Application.AddIns("Upload Button") Exists Then
     Application.AddIns("Upload Button").Installed = False
  End If
  </code></pre>
  
  <p>Hit me back!</p>
  
  <p>EDIT: I solved this using On Error Resume Next</p>
  
  <pre><code>On Error Resume Next
  Application.AddIns("Upload Button").Installed = False
  On Error Goto 0
  </code></pre>
