I'm running Windows 7 Pro 64bit. 6gb ram, Poser 2012 fully updated. The other 3 machines are running Windows 7 32bir, 2gb ram. Nothing else is installed on the other computers. I run the 32bit version of poser render queue on both 64bit (main computer) and32bit (3 render computers) I don't believe there is an issue with 64 and 32 bit, but my question is, should I un-install the 2005 and 2008 versions of C++ and then install the 2010 version, or just install the 2010 version?
