Roon trial won't install

I’ve downloaded the trial app 3 times now and it won’t install or run. I’m running it on a Mac Mini (late 2012) with 8GB memory and an i7 processor with OS X 10.11.1 (El Capitan). I’ve tried rebooting and following the steps on another topic “Roon quits on startup on macbook pro” to no avail.

Found another thread that suggested dragging and dropping the Roon icon into the applications folder and then launching from there. That seems to have worked. Now loading. Would be useful to have some instructions in that regard! I’ve loaded multiple applications on our multiple Macs, iPads, etc. and never had to do that before
