Well, the problem I’ve been having with the Open World Demo Collection showing up in my on-line and allowing itself to be applied to my project but never showing up in the engine or on my hard drive has been solved.
The Open World Demo Collection presents itself in the engine and on my system as KiteDemo473, go figure.
So if anyone else is having this maddening issue and is getting nowhere googling asking for help, you can stop now.
Hope it helps
