Well, after an EXTREMELY long and convoluted installation, I clicked the K3D icon on my desktop and immediately received an error message that said "The procedure entry point XML_SetDoctypeDeclHandler could not be located in the dynamic link library xmlparse.dll." Hmm. I also found that there's no easy way around that error. So, until the the developers can get the program to launch reliably, I advise that you stay away from K-3D and, instead, find an alternative 3-D graphics program.
