AdobePDFMakerForOffice in Microsoft Visio

Question

I gather from rummaging in these forums that AdobePDFMakerForOffice is not officially supported so I'll throw this to the community and hope someone has a suggestion.
With Acrobat XI installed, the following VBA code works correctly in Microsoft Word, and with very minor changes, also works in Excel. However, it does not work in Visio. In Visio, the code finds the COM AddIn successfully, but COM.Object is Nothing. Consequently, the assignment “Set pmkr = COM.Object” does not create an error, but pmrk is Nothing.
Any ideas why the code finds the COM addin but the object is null?
BTW, if you run the COM AddIn from the Acrobat tab on the Visio ribbon, it creates the PDF correctly.
Thanks,
Scott
