When you create a PDF in a Microsoft Office 2007 application using the Acrobat > Create PDF option, PDFMaker quits silently and no PDF is created; or PDFMaker returns the error "An unexpected error has occurred. PDFMaker was unable to produce the Adobe PDF."
Alternatively, when you attempt to create a PDF from multiple Word files within Acrobat, you receive the error "Skipping file."
If you are attempting to create a PDF from within Acrobat using Microsoft Office documents, then make sure PDFMaker is properly installed in the Office application. Refer to "PDFMaker is unavailable in a Microsoft Office 2007 Application after installing Acrobat 8.1" (Technote kb401734) to enable PDFMaker.
