Adobe Acrobat DC for Mac: Error 32815 observed in Microsoft 365 Word, Excel and PowerPoint

Each time Adobe Acrobat Pro is installed or updated, the Acrobat Add-in is silently added back to the Microsoft 365-related User Content Startup folders on macOS.

The Add-in relies on external dynamic libraries — which we purposely disable by setting DisableVisualBasicExternalDylibs to true — causing users to observe error message 32815 in the following applications:

• Microsoft Word
• Microsoft Excel
• Microsoft PowerPoint

Adobe should first check if DisableVisualBasicExternalDylibs is enabled before installing its Add-in:

❯ defaults read /Library/Managed\ Preferences/com.microsoft.office.plist DisableVisualBasicExternalDylibs
1
