Now i see why Apple have removed the run apps from 'Anywhere' option in Mac OS Sierra. I don't know why you would run with that option turned on unless the user has been told to by an idiot. Keep Gate Keeper set to App Store and Identified Developers only, if you need an app from else where and absolutely trust them just right click on the app and select Open, then an extra open option appears instead of being blocked with only an OK box. Simple and no need to compromise part of the security.
