I have used NOF for many years. I started with 7, upgraded to 9, then 11 and finally 12. I have the original CD for 7 and the 9 upgrade and burned CDs for my 11 and 12 upgrades. I now have a new computer with Win8. Do I need to try (if it will even work) to install 7 and move through all the upgrades or can I skip some? Any help would be appreciated.
