I am compiling an AIR application from Animate CC (mac version) with runtime embedded. No issues on the mac, but when i transfer the app file to a PC (running windows obviously), the app icon displays as a folder instead, and there is nothing within this folder that I can click on to run the app.
I was under the impression that Adobe AIR is cross platform compatible, so am I doing something wrong when compiling, or do I have to compile on a PC to create a runtime embedded app that will run on Windows?
It's impossible to launch Mac app on Windows. Because embed runtimes are different for Win/Mac. Here you can get some more info https://superuser.com/questions/56739/executable-files-in-mac-os-x-vs-windows.
So you either build 'Mac projector' and run it on Mac or 'Windows projector' to run on Windows (you can change this option in File -> Publish Settings). Tick both options and you'll be able to run it on Win and Mac.
One more option is to build AIR app - but it will require AIR runtime installed.
