PDF problems - Troubleshooting

Symptoms: Trouble opening a PDF file posted on a Moodle page

The cause is almost always a problem with the Adobe Reader plugin. Adobe Reader can easily get "out of synch" with your browser and stop opening PDFs within the browser.

Here are some fixes to try:

1.      Installing the latest version of Adobe Reader almost always solves the problem.
   
   Any new updates to your system (including Java, QuickTime, browser, and Windows updates) that happened after you last installed Adobe Reader can cause the problem to occur again.
   
   Go to http://get.adobe.com/reader/ to re-install Adobe Reader and see if that solves the problem.
   
   
2.      If it doesn't, try switching to a different web browser. We recommend:
3.       Chrome, which can be downloaded from https://www.google.com/intl/en/chrome/browser/ and
4.      Mozilla Firefox, which can be downloaded from http://www.mozilla.org/en-US/firefox/new/
   
   
5.      If that doesn't work, set Firefox to always open Adobe PDFs within the Adobe Reader program (so it stops trying to open the file within itself):
   
   
   
6.      On a Windows computer, open Firefox, go to the Tools menu, and select Options.
   
   
7.      In the Options window, click the Applications button at the top of the window.
   
   
8.      Select Adobe Acrobat Document, and choose Open in Adobe Reader from the drop-down menu that appears to its right.
