Need help with workaround - Offline Installer failed on Mac laptop

Question

I have a student who can't get the offline installer to work on her Mac laptop: OS High Sierra 10.13.6

Wwise installer "can't find bundle.json" even though the file is in the zip archive and clearly where it's supposed to be.

I can install easily from this same zip archive package on my iMac teaching station without any errors.

Is there a workaround or hack that anyone knows?

The procedure we've been using is to use the "Start Offline Installer" feature under Versions Installed in the Wwise Launcher.

Wifi on our campus is spotty so re-downloading over the internet is an option I'm trying to avoid.

Also, I'm a PC guy but can make my way around a Mac fine. Just let me know where to look.

Many thanks!
