Mac Projector created in MAC doesn't work on Mac

I've made a projector file in adobe animate that's a sort of interactive asset for clients that need to run it on mac or windows. Windows users have no problems running it with the .exe. But Mac .app is impossible to use!

I can open the projector file fine on my own Mac, but when other Mac users try to open it they get an error message saying.  ""Video" is damaged and can't be opened. You should move it to the Trash.". 

As a note, this is to be used in corporate laptops for a sales presentation, so the users are not allowed to install, or do weird things with their machines. 

What can I do? Help please!
