Hi Christopher,
You have said in jira comments that if installer is being build with Air 27
everything should work fine. I have build new version of installer with AIR
25 and Flex 4.16. It worked perfectly fine on my Mac Sierra. I will try to
build version with signed keys and see what happen.
I tried using the instructions for building the installer with ANT and used
AIR 4.0. With that version of AIR, it fails on OS 10.13.
When I ended up building with AIR 27 it works on 10.13, which according to
the AIR 27 release notes[1] states "With AIR SDK 27, all AIR applications
built for macOS
