My previous answer was based on incomplete information. The Acrobat add-in creates the Acrobat tab on the Ribbon. This tab is the only way I know of to include both hyperlinks and fonts in a PDF created from Word for Mac.
The first step is to open Adobe Acrobat (Yes, Acrobat, the full version. No, not Acrobat Reader, no, not Word) and choose Help>Check for Updates. This should replace the old add-in with a new one that doesn't raise the error.
If the update doesn't make the Acrobat tab appear, re-open Acrobat and repair your installation (The command location varies with your edition of Acrobat).
If you no longer have a full copy of Acrobat installed, then proceed with the following advice. If updating Acrobat doesn't fix the error message, proceed with the following advice. Below is the response that was originally marked as an Answer:
The latest edition of Acrobat PDFMaker appears to be incompatibile with Word and PowerPoint. To fix this:
- Start by closing Word.
- To open your hidden user Library folder, hold down the Option key while clicking on the Go menu and choosing Library. The folder will open.
- Open ~/Library/Group Containers/UB48T346G9.Office/User Content.localized/Startup.localized/Word. Please note that the User Content and Startup folders will not always have .localized appended to the name when you view them in the Finder.
- Drag the Acrobat add-in file to your desktop, then restart Word to test that the crash is gone.
For PowerPoint, the path is almost identical, but look in Startup.localized/PowerPoint.
