A 32-bit Windows version should work fine running in Wow64 mode.

A native 64-bit Windows version of Erlang/OTP was not possible
last time I checked (late last year). The problem is Microsoft's
decision to make the C 'long' type 32 bits although pointers are
64 bits. Fixing this is easy in principle (use uintptr_t), but
requires a lot of tedious work and rigorous testing, so I suspect
it will take a while before that happens.

Perhaps run a 64-bit Linux/Unix version in a VMM on Vista/x64 instead?
