I have NIS installed on 3 Desktops. On my Win8 tablet I am running a trial version of NIS. It is working great and I want to add another license. What is the best option for doing this? I don't want 360 and tablet security is not an option with Win8. I just want NIS. Would upgrading NIS to 5 PC's be the most cost effective? I can't find this option anywhere for upgrading and sales is not understanding what I am asking.
Any help woudl be appreciated. Thanks
