Ok I think I got it - you actually need this slightly updated version of that last one:

I took a look at some of the guts of that 3dm2sculpt.exe and it was depending on the SP1 version of these DLLs, the previous link I posted was to the original (SP0) version.

It would probably be a good idea for that .exe to be rebuilt using the "static link" CRT option instead so that it would have everything build right in to the .exe instead of needing this additional install.
