My HP Pavilion dv6000 running Vista Home Preimun with a HP Photosmart C5100 printer. Adobe Reader 8.1.2 opens pdf files in various languages. These files were sent in English and I can forward to others who use Microsoft XP and they do not have any problems opening these files. I have installed and uninstalled Adobe 8.1.2 (3) times with no change. I have confirmed that Word is the HTML eiditor preference. My fire wall and virus scans don't indicate any problems. What should I look at next? Is this an Adobe software issue?
