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, 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/Group Containers/UB48T346G9.Office/User Content/Startup/Word.
- Drag the Acrobat add-in file LinkCreation.dotm to your desktop, then restart Word to test that the crash is gone.
For PowerPoint, the path is almost identical, but look in Startup/PowerPoint.
