Mac can't open producer 2003 published presentation

[Dave]

I produced a presentation in Producer 2003 to a CD. A Mac user with
• Apple Mac OS X v 10.2 or later.
• Windows Media Player for Mac OS X.
• Internet Explorer 5.2.2 (or later) for Mac.
tried to open it, but couldn't. Does anybody have any idea what I may have
done wrong when I used Producer? It's supposed to produce presenations
viewable by a Mac.

Thanks.
