NV2 currently does not run on an IPAD. I have tried NV2 on linux (Ubuntu) which does run using a program called WINE but some of the help screens do not display properly. You may be able to install WINE on your IPAD and run NV2 (after transferring your data to a server machine) and use NV2 on your Ipad3.
You will have to register NV2 on the IPAD and email me at email@example.com of the results.
NV2 at the moment is a windows only program.
A new update called NV3 is comming within a year.
I hope this helps!
Regards to All,
