Sorry but 32bit is mostly dead.  It only makes sense when a program doesn't need or use lots of memory, Poser does.  I sympathize with folks that can't upgrade, I've been there, but 64bit processors and OSes have been out for nearly a decade.  Companies need to walk that fine line between supporting their base and moving with the times.  I suspect the majority of Poser users have 64bit CPUs and OSes, time for Poser to move on.
