Likewise I read as is .. lol

I've never seen nor created a corel slideshow. And yes I'd agree exe files are not a good idea on their own. Zipped or whatever is much wiser. By default, LW gives warnings about downlding exe files & many users would take heed of such warning.

So what do you need to play these presentations? They sound like independent self-executing files. Such as a Director projector but a lot simpler.
