I don't have Poser 5 yet so I'm not familiar with the registration stuff. I do know that my systems guy made disk images of entire drives for me. He also backed up the registry. This enabled us to reformat drives and just dump the disk image onto it. If the disk image was made on the drive with the os we didn't have to reinstall windows as it was in the disk image. Just a suggestion that might help. If you're interested I can get the name of the software he used to make the disk images. Good Luck.
