The VBM Add-in will not load or show in the Add-in list if you are running 64-bit Office and Outlook.


So long as the user has a 32-bit version of Office and Outlook installed on their computer that is compatible with the version 2 of ADVANTAGE VBM installed on the computer, Office and Outlook are considered compatible with ADVANTAGE VBM. This includes 32-bit versions of Office or Outlook installed with Office 365.  


Check with Microsoft to find out if you really need 64-bit Office or Outlook.
