Hi Dino, As I understand it, there are two phases to building an AIR app. The first phase is building a SWF. The second phase is packaging.
I have not tried it myself, but one thing you can try is using Flash Builder with Flex 4.0 and whatever AIR SDK came with your Flash Builder to build the SWF. SWFs are not 32-bit or 64-bit. Then, without Flash Builder, run a script to do the packaging with a newer AIR SDK. If you use Apache Ant as the scripting language, you can launch that script from Flash Builder.

We try to set the environment variable AIR_ARC_WIN = 64, in the o.s., but have no effect and the build of air application is again at 32 bit. I have found a work around in the merge the flex sdk 4.6 with air sdk 31.0 beta and building a captive application air and then we have finally a 64 bit application (but the distribution of this kind of app is very more difficult and the upgrade of the library from 4.0 to 4.6 take it problem of compatibilty). If you have any suggestion to solve this solution, please reply me.
