Renew/Updates For Norton Products(NIS For Mac, NIS 2012, & NU v)

Hi,

 

I have NIS 5 For Mac, NIS 2012, & Norton Utilities v15.

 

And I have installed Windows Pro 8 and OS X Mountian Lion on my computers.

 

So the questions are:

 

Where and how do I get the "Latest updates for the products I have"?

And,

 

How do I renew my products?

 

Thanks.
