I too thought that 321 Studios was no longer able to be installed, but after reading a few threads about others still using it, I installed in on 2 of my computers again, and it still works. Had no problem with registration at all. It was my first DVD coping program and it worked fine then and still works just as good. I have since found other software that works better/or just as good and it was free. So either way at least I still have what I paid for and I also have another choice as to how I can copy my movies.
