I am using Word 14.4.5 (the latest version of "Word 2011"). Since installing that version of Word four years ago, I often create PDFs from Word files using the File > Print command of Word.
Adobe help says:
PDFMaker
PDFMaker is not available for Mac OS. However, you can still create PDFs from many business applications using the File > Print command. In the Print dialog box, choose Save As Adobe PDF from the PDF menu.
(Note: I don't use the Save as Adobe PDF choice; instead I use Save as PDF...
I just tried Save as Adobe PDF. It works fine (though it adds additional steps to the process).)
