How to open Elearning Bundle

I purchased the e-learning bundle and downloaded it as a zip file. I’'m on a Mac. When I try to open it it tells me I have no application associated with it. Can anyone shed any light on this - cause otherwise I’ve just blown $120 bucks on tutorials I can’t open…

Hi , I am not a MAC user but did a little technical support , I think you need
Stuffit expander .
