The end of the story. Late yesterday evening I was answered by the administrator Marcos on the European site Eset and promised to understand the situation and help. Today at noon on the Russian support forum, the administrator asked me if the key had come? I checked my mail, there was no key. I said that now the situation will be sorted out from the head office in Slovakia. A couple of hours later they sent me a new key. Sent by the leading technical specialist of the 1st line of technical support (there was such a signature in the letter). We apologized for the long delay and inconvenience caused. And I was about to write a complaint to their director ... Successfully activated the license on the website, then in the antivirus. The antivirus accepted the license, wrote that it was valid for 3 years until 2025, but immediately refused to update the anti-virus databases, displaying an error message about updating the databases, hinting that something was wrong with the license
Apparently there was a glitch him
I rebooted the system, but after the reboot, when I tried to manually update the databases, the antivirus gave an update error, again hinting at the license. I already opened the Russian tech support forum to write an angry message again, but then Eset got scared and updated the databases
This is where the story ends. However, I still need to activate licenses on two other computers of those people who together with me threw off the purchase of a license. And if, when activating the antivirus on their systems, Eset fails to activate, then you will find a fascinating continuation of the story with technical support
