Did you extract it first and then run it? Also, what error did you encounter? Is it just not opening?
I'll try to to investigate the problem. In the meantime ,can you try to ensure that its not "unallowed" in settings?
Allow the app in System Preferences > Security & Privacy > General > Allow "...<app name>"
if that doesn't work, try to open the terminal and type:
"chmod -R 777 AtomiQuest_mac_full_1_2.app"
