I have a Win 7 desktop and a Win 8 laptop. I run NOF 12 on the Win 7 desktop because I understand it is not compatible with Win 8. Now I would like to move NOF to the laptop since NOF 13 is compatible with Win 8. If NOF 12 is not compatible with Win 8 how can I get a version on the laptop that can be upgraded to NOF 13? What is the upgrade path or would I need to buy another version at full price? Thank you.
