Unfortunately Adobe has decided to limit the ability of the ".air" files such that they can't run native code. And because TurboActivate talks with the hardware on the computer to do the hardware locking it *must* be a native library.
Thus the only option for Adobe AIR apps is to use the native installer. One of the advantages of a native installer is that it allows people who don't have the adobe AIR runtime installed to run your app.
The downside is, of course, you have to make your installer on Windows, Mac, and Linux. This is a limitation of Adobe's tools. We're hoping they'll fix these problems.
