Can't open avi movie

I'm able to create avi movies with photopaint and to open the ones I create. 
However, I can't open one I obtained from another source.  The error message 
I get is:

You must use the control panel to install support for audio and visual 
compression.

What control panel does this message refer to?  I looked at the add remove 
program control panel and didn't see an option for adding support for audio 
and visual compression.

I have the academic version.  Could that have anything to do with this 
problem?
