Have bought the 3PC upgrade the 'old' 2010 version for unbeatable 12,90. With me already ran a upgedatetes NIS2010 Netbook Edition (ie NIS2011NE), an update to this specific version, I had not found a thought experiment would be worth it. Uninstall emergency Netbook Edition, install normal version. Entering the new product key in NIS2011NE not work as expected. (Disabled whose function first! So old Key again reingetippt, 5 days remaining term back in it.) After inquiry in Norton Support Live Chat (accessible via Service and Support -> lower left 'Contact') if I had to reinstall my licenses were offered to transfer to my just leaking "Norton Internet Security Netbook"! Prima! A brief update of subscription status in the program itself - and the protection and running again for a year. Maybe I was lucky and the right support staff caught ... ists feasible in any case. And: According to product description you with Subscription are entitled to the latest version (including the 2011). So a super tip for bargain hunters, valid (Alt) license required!
