The License keys tab serves to manage license keys for other ESET products, such as ESET Remote Administrator, NOD32 for Kerio mail server, NOD32 for Kerio Winroute firewall, etc. The window provides comprehensive information about particular license keys, such as the product name, registered owner, volume of licenses as well as the date of expiration.
To add/remove a license key, click on the corresponding button of the license manager window. If you are interested in purchasing ESET products, click Order… You will be redirected to the online store website (the Order… button is only available when a license key is expired).
