Multiple Activation Codes

I am setting up a system that was purchased at a local "SuperStore". The customer purchased NOD32 AntiVirus 4. He was provided with four disks with four activation codes. According to the salesperson this is a four year license. How do you enter multiple codes on a single install?

Thanks for any suggestions.

 

He was told wrong - these are all 1-user codes. The only way to get 4 years is to activate one, install - wait a year, activate the next - enter the next username/password - wait a year - repeat.

ESET does not offer 4 year licensing - the most they offer is 3 year - and the "superstores" have 1 and 3-user packs in 1 year ONLY to my knowledge. Trusting what the retailer knows in superstore is a road to frequent disappointment in my experience and I fear in this case it will be also...
