Edit Answer (for another -22 minute) It is possible to open the Docx document in Word and use word to save it as a PDF. There are also other office suites that can open the Docx format and save it as a PDF. look at Apache OpenOffice.org. It appears you are trying to open the DOCX with Adobe Reader. Adobe Reader can only open PDF files.
