Garmin Express for Mac Won't Install

So I just finally got around to setting up one of my newer computers. Downloading the old Garmin Express and hoping to load the Gmetrix from my Fenix into my Virb video.

When trying to install on the last step it fails and says I need to be admin, which I totally am. I did recently upgrade to Mojave 10.14.

Anyone else having similar issues? Or should I keep poking and prodding.
