You must save the PP as a "package." Then, take the entire folder
(package) with you on your flash or CE to play it on the other
computer. That way, all the files, including the audio file "travels"
with the PP in that folder -- when you try to play it someplace else,
the PP program goes to the original place where the audio file was to
get it to play. If you are on another computer and you only have the
PP program withOUT the audio file, PP still tries to find it by
looking for it in it's original place where you had it when you
created the PP, and it cannot play it because while you are in Jamaica
with your powerpoint, your audio file is still on your home computer
in Nebraska (for example!). So Save it as a PACKAGE and take the
entire PP folder that is made with you.
How about to convert your powerpoint to flash?
Then the viewer is still able to click along at their own pace.
