Well, to be honest I've never tried a 64-bit Windows machine.

Even though my trusty WinXP wouldn't run any of it, I could release a 
64-bit ADMB-IDE, in both zip and exe format.

The first step would be to find mingw64. At first glance, it looks like 
two websites offer a variety of mingw64, but I'm not in a position to test 
which one works:


Some of those archives seem large and may contain unnecessary components. 
I've tried to make ADMB-IDE as small as possible, not including Fortran or 
the like.

The next step would be to build ADMB for 64-bit Windows. Based on 
someone's success with the first step above, Johnoel could probably roll 
out admb-9.1-windows-mingw-gcc4.4-64bit in both zip and exe format.

This would probably be worthwhile, mainly for people with 4+ GB of RAM and 
models requiring the same. Based on various benchmarks, I don't expect 
going from 32 to 64 bits will result in much speed improvement, but who 
knows. But when it comes to such heavy models, the expected 60% 
performance gain by running in Linux rather than Windows is worth 
considering. You could still do everything else in Windows, like preparing 
the model input, analyzing the output, writing up, etc.
