[python-win32] Outlook Add-In Demo Question ... A runtime error occurred during the loading of the com add-in

Thanks for verifying!

Mine is a Desktop version...  not 365 (installed with Product Key not subscription as part of Office Professional Plus 2019)

Right.

Is this the desktop versions or the Office 365 versions?  There are
