Hey Jones,
Reading some instructions I found that to incorporate Turbo Activate I will need to create a native build for my app (exe/dmg/rpm) that runs Native Process, rather than exporting to .air.
That's correct. The current version of our TurboActivate / Adobe AIR integration requires the native installer due to limitations in the Adobe AIR design. It is really unavoidable.
In the near future we're adding the ability for non-native installer distribution for Adobe AIR 3.0+ (see: AIR 3.0 = LimeLM for AIR (not native) apps?).
Do you know if there's a workaround for this?
You can always wrap their native installer with your own native installer. That is, you include the *.app file with their native installer output. Does that make sense?
Or you can use Adobe AIR 3.x and use the new Adobe AIR extension behavior.
