Bought a boxed version of Norton Antivirus...few questions

I have a 2 year license for Eset NOD32 so I don't want to use my Norton Antivirus license right away, I just bought it because it was a special offer for $15 USD only

 

Question 1: What is the validity of my license? how long can I wait beore activating it?

 

Question 2: I don't want to install Norton Antivirus that came on the CD where do I download the latest Norton Antivirus from?

 

Question 3: What I like about NOD32 is that I can activate it as many times as I want as long as it is on the same computer with the same computer name and same specs, I know some other AVs I have used like Kaspersky Antivirus have a limit of like 7 activations then your license is blacklisted and blocked. The reason I ask, because I tend to format a lot for testing diff. drivers software sometimes, what is Norton's rules on activation? are they lenient like ESET or strict like Kaspersky?

 

With my Bitdefender Antivirus, after installing it, when I don't need it on that PC anymore, I can login to my account online and de-activate it so I can install it again later on

 

Question 4: I created a Norton Account and obviously it has no products registered in it, how do I go about registering my license key that came in the box on my online account?

 

thanks
