-In the Windows registry (Press the Windows key on your keyboard with the R Key to bring up the Run  box then type in Regedit and press Enter), find the default entry in the below key to confirm the correct Outlook version reference.
 

For example: 

  • 9.4 for Outlook 2010 or 9.5 for Outlook 2013: HKEY_CLASSES_ROOT\Interface\{00063001-0000-0000-C000-000000000046}\TypeLib 
  • For a 64-bit window: HKEY_CLASSES_ROOT\WOW6432Node\Interface\{00063001-0000-0000-C000-000000000046}\TypeLib



Important: Be sure to check the version of Outlook:

5. Delete the version keys (e.g. 9.5 OR 9.4) for any version of Outlook that is NOT installed on the user machine based on the above version table.

DO NOT DELETE the entry for the version we found in configured in Step #3
