My licence for ESET Multi Device Security (5 devices, 1 year) will be over in less than a week and I want to renew my licence. I searched through online retailers in my country and all the products I see contain licences for either version 10 or version 11. I cannot buy using ESET store since I cannot use a credit card (I know I would get a licence for version 12 on ESET store). My question is, can I activate ESET Internet Security version 12 on my PCs using a licence for either version 10 or version 11? (version 10 is preferred since it is sold as a boxed copy)
Also I want to ask that can I use the new licence in the box as a renewal since it provides extra 4 months of protection that way?
