How do I create a 64-bit Captive Runtime Bundle?

Hello,

I've been trying to get my head around memory usage in Windows, which led me down a rabbit hole to this question.

As I understand it, applications in 32-bit Windows are allocated 2GB (which can be increased to 3GB with the 4GT setting), but a 64-bit application can make use of a lot more (depending on the version of Windows).

So my main question is how do I create a 64-bit Captive Runtime Bundle (where the whole AIR executable files are packaged in the build folder).

And for bonus points, will this application then make use of the extra memory available?
