Hi, I'm almost ready to purchase some licenses for the Business Edition of NOD32 v3. However, I liked V2 very much when I evaluated it some time ago and intend to keep using it for low-end machines. Is it possible to use V2 with a V3 license ? Also, I'll order several licenses at once but as my network grows, I may need to purchase some more. Is it possible to extend the number of computers my previously bought license covers ? Thanks.
