I read it, but he said most users, not all users. He could offer the 64 Bits
version as Pro version at an additional cost for example if it trakes too
much effort. MS kept int/long the same size in the 64-Bit compiler, so in
many cases, not much code change is required to port the code to 64 Bits.
Only pointer size changed.
