Now that the updated version of the Add-In can be detected & installed, I need to:
  1. Uninstall the previous AddIn
  2. Delete the previous AddIn XLAM from the Users Library path
  3. Delete the previous version entry in the AddIns Library

I don't expect any difficult with 1 & 2. However 3 is a different matter. Leaving aside the possibility (if it is one) of detecting & deleting the registry key for the old addin entry, does any one have any suggestions? (As a starter, I am toying with the idea of trying to "install" the previous addin after the XLAM is deleted and then using Send Keys to select Yes to the message ~ your addin is missing, do you wish to delete this entry)
