Crashes from App Store, Runs from Launchpad

The ‘crash on startup’ bug that others are reporting seems to be limited to launching from within the App Store screen. If you click the ‘Open’ button from the App Store window after downloading then the App crashes instantly without any warning or eror message. If you close the App Store window, open Launchpad, and run it from there, it seems to run fine.

Works fine with High Sierra

Was uncertain about using this given some of other reviews suggesting problem using this with High Sierra. But I installed it on a 2016 MacBook Pro and a 2013 Mac Pro both running High Sierra and the software imnstalled and ran fine on both. Gives easy and clear results. Very helpful when running a range of drives connected to both Macs.

Does Exactly As The Reviews Say

You know when you read the reviews and you think ”I'm sure it will work for me”. It won’t. Unfortunately it does crash as soon as you launch it.
