- Start by closing Word.
- To open your hidden user Library folder, Go to the Finder (leftmost icon on the dock with blue/white face) and hold down the Option key while clicking on the Go menu and choosing Library. The folder will open.
- Open ~/Library/Open Group Containers/UB48T346G9.Office/User Content/Startup/Word.
- Drag the Acrobat add-in file LinkCreation.dotm and possibly also SaveAsAdobePDF.ppam to your desktop, then restart Word to test that the crash is gone by opening a new blank document.
- If the same error occurs, go to the Tools menu>Templates and Add-ins, and untick the boxes for the add-ins. If there are others for EndNotes or Zotero, leave those alone.
- Quit again.
- Restart Word
- Repeat steps 1-4.
For PowerPoint and Excel, the path is almost identical, but look in Startup/PowerPoint and Startup/Excel.
