I don't see how that helps me. It tells me where the exe is that will act as the viewer but if there isn't one it gives an ugly error messege. I need sort of a true or false kind of answer that I can use to trigger an install dialogue.

It's for Acrobat Reader, but just substitute the .pdf for .ppt and I bet it'll work.
