Norton Internet Security 2012 Trial

Hi

 

I need to dowload the non credit card trial version available at this link:

 

www.norton.com/nis12

 

(I use the non c/card trial as I install it for many customers who then go on to purchase it themselves)

 

But this trial version is nearly 6 months out of date and the updates are bigger than the programme(!), can it be updated? Or is there a better link to a newer version?
