Is the product key I received O.K. for my desktop P.C.?

I purchased a new product key for my desktop computer.  When I received my product key it came with a download link to www.norton.com/netbook. 

 

My concern is that the product key is for a netbook version of Internet Security and not the desktop version. Or are they one and the same?

 

[Incidently, this is a subscription renewal and so I would be typing the product key directly into my preloaded NIS rather than using a download.]
