I am trying to get RingCentral Rooms to install silently / quietly, using the latest 19.4 MSI installer.

I have tried running it with the /qn switch, but it still pops up with the install options page.

The other RingCentral produts MSI installers work with the /qn switch, and install quietly. It would be nice if I could get the Rooms installer to work as well.
