How do I obtain a license key for the Business Editions of ESET security products?
License keys (nod32.lic file) are issued as attachments to license emails. These emails are automatically sent to the user’s registered email address after the purchase of NOD32 Antivirus Business Edition or ESET Smart Security Business Edition. To receive your license email (with a license key attached), please complete the form at http://www.eset.com/support/lost_license.php.
