Hi Len, actually I think quite a few people would find a 64-bit version useful, MoI is used pretty frequently as a way to transfer CAD data to rendering programs and it's not unusual for the imported files to be pretty huge and detailed.

So it's definitely not that it would not be useful, the problem is just that it is heavily time consuming work for me to produce it.

It's mostly an "all or nothing" kind of a thing too, you can't easily make just one portion of a program 64-bit. When the main program is 64-bit all the support libraries that it uses and all DLLs that it calls directly into also need to be all 64-bit as well.
