Worth a try, since it's free.
I have a pc Powerpoint 2007 presentation which needs to be read on a Mac running Lion 10.7.5, What is the best (free) software solution. I do not believe the recipient has Mac Powerpoint installed on the Mac at this time.
It is essential to preserve the animation, images and sound with the presentation. No editing is required, only a reader or viewer for the presentation.
I have already converted the Powerpoint converted to a pdf, a a backup reference plan.
