I think the other responder was suggesting that I copy the pelles folder under Programs on the xp machine and just put it in the Programs folder on the windows 8.1 machine. I do not understand how this would work because the pelles program has not been 'installed' on this machine. To me, a non-guru, I think 'install' means integrating the program into windows 8.1. If I am wrong, I would be glad to hear a proper explanation. Thank you for responding.
