I have a lecture which is a PDF file, where the audio is embedded in the slides. Why can't I open it?

Some lectures are set up using an Adobe presentation and you may have trouble accessing/opening them. 

There are several things to try in this case:

  1. Use Mozilla Firefox  as your web browser. While Google Chrome is fine for most things, it seems to be incompatible with these PDF lecture files.  Safari in a MAC computer should also be fine.  Do not use Internet Explorer.   If you do not have Firefox, download it here
  2. Upgrade to the latest Adobe Reader:  click here to download that.   
  3. Ensure that you have the latest Adobe Flash.  If you cannot see the audio of the lecture, which is usually on the second page of the file, you do not have Flash.  Download here.
  4. Once you are sure you have the latest versions, as above:
    • Download the lecture file and save it to your computer
    • Locate the file, and right mouse click on it, and select: Open with Adobe Acrobat Reader

Ensure you do this way or the file most likely won't open fully, or with a blank page only.
Please see this video of the steps that you need to do:
