Export Windows native installer from MAC

Hello,

I am developing an desktop app that needs to be compiled into Native installer (because i'm using NativeProcess class).

The fact is that i am working on FB4.7 OSX and i'm only able to compile the Mac version of my app (into .dmg file), and not the windows one...

Is there a way to build that Win version from my mac ?

(it would be a shame not to be able to export both versions, or my conception of AIR is wrong...) ?

Thanks,

Arthy
