Went thru the install ok, received confirmation that the install was succesfull. But the black shield icon is not on the menu bar or desktop.
So I am not sure it was installed.

You may be confusing the menu bar and the application dock -- the menu bar goes along the top of your monitor, and the shield icon should show up near the time display on the right hand side. The dock is on the bottom of the screen by default, and you'll see icons for any applications currently running plus any you've dragged to a position on a dock (these will stay there permanently, whether they're running or not).
