It won't run in a DVD player as the file is a programme rather than a movie format file. Needs the interactivity, mouse controls Etc., of a computer.
Whilst this may annoy some, it was a product of what we wanted the CD to be...an interactive course, not a DVD movie you pop on and sit in front of and watch.
The idea here is that you watch...go away and do...recap if required, do again...and so on until finished.
