Hi Deuce, yup what Ed says above is correct - there is currently only a 32-bit version. At some point in the future there may be a 64-bit version but not anytime soon, there are actually a lot of other feature areas that will help with things for large model handling more than being 64-bit, stuff like instances for example.

Even the 32-bit version does benefit from running on a 64-bit OS though, MoI is able to access about twice as much memory on a 64-bit OS than on a 32-bit OS.
