Just to clarify, by "activation" I mean to use the licence again on the same computer. I am not talking about piracy, lol.
The first time, Kaspersky support allowed me additional activations on the same computer (without extending the time). The second time:
This was the official Kaspersky response:
Dear customer,
Kaspersky customers who chose to purchase products on eBay sometimes encounter an issue with exceeded activation limit. This issue is caused by the fact that many eBay sellers simply resell the same activation code for a Kaspersky product to multiple customers at reduced price. When multiple customers use the same activation code they very quickly exceed activation limit.
In order to reset activation counter we need to get one of the following things:
1) A snapshot (photo) of the 20 character activation code on the package, as it is (for box versions);
2) A screenshot of original e-mail from official Kaspersky e-store (for digital purchases).
If you don't have this information, unfortunately, we can't help. The only solution is to contact the eBay retailer/seller for a refund of your purchase.
We are sorry for any inconveniences.
If the suggested solution did not help or you need more information, you can simply reply to this e-mail leaving the subject line unchanged.
If you have no further questions and the issue is in fact resolved, then you can simply ignore this message, and we will close this request for you within 5 days.
Best regards,
Kaspersky Lab Technical Support
