NIS2011 Upgrade is a successful product. Since there is nothing wrong.
In particular NIS2010 users come with this product low for another year effective protection.
2Point deduction I admit, however, for the very poor installation!
There seems to be Windows versions where NIS during the installation no way offering to enter the product key. (Available on the CD back on it). Only with this input, the account status extended for another year.
Well now is good advice. Nowhere you will find a guide to. Sits like me Saturday before the PC goes at Norton also ran no more. There one can find a wolf then.
Here the solution: Open Norton Center. Bottom left (next to the Norton Logo) on "Extend" button. In the appearing window then perform Option 2 and enter the product key. Done.
User-friendly looks different.
