Thanks so much for your reply. It would seem that it should work, but they seem so concerned about one program, one computer, that it worries me if I download and save to my computer and try to copy and install it on my grandson's computer that it may not pass all the security requirements.
The last thing I want is a very disappointed grandson on Christmas Day.
I have just purchased my first copy of anything from Reallusion - Crazy Talk Animator. I have not found a way to contact anyone official and get an answer back. This is a worry to me as I begin my investment in this product; for hobby and recreation purposes only.
