1. In the Finder, do a "Find" for "PDFMaker". You will probably discover
These annoying files in three Startup folders (Word, Excel, PowerPoint),
namely PDFMaker.dot, PDFMaker.xla and PDFMaker.ppa Trash the files.
2. In place of each of them, create a new blank *folder* with the names,
respectively, of PDFMaker.dot, PDFMaker.xla and PDFMaker.ppa.
3. When you open Acrobat you may be told there is a discrepancy and asked
whether you want it repaired. Click "Don't ask me again" and "No" to the
repair question.
The result is that when you open Acrobat, it will "see" that you already
have a PDFMaker.dot or .xla in folder form and will not create another nor
overwrite what's there (since a file can't overwrite a folder).
