@diff There may be 3 devices if the subscription was activated a long time ago with KSC Free.

Correct, that must be the reason.

Apparently you had a license for Kaspersky Security Cloud Free. It did include three devices. This product no longer exists. That's probably why the restrictions have changed.

I see, in my account it reads 3 devices instead of 2. Thanks

Thanks the responses, I only have 2 linked devices in My Kaspersky, but I can not link another one. I asked the support team, but they did not give me a solution, just invited me to ask in this forum. Maybe the reason is what you point out about Kaspersky Free being deprecated. Or maybe only 2 dives are allowed as Andrew75 says. Thanks again

A Kaspesky Free subscription cannot include more than two devices. To activate Kaspersky Free on a third device, you must use a different account.

Welcome to Kaspersky Community. Check in My Kaspersky -> Devices, the devices linked, if still connected, just disconnect and re-link again. But maybe can be also because Kaspersky has just “deprecated” Kaspersky Free product, still the installed products will continue working, but installers are no longer available.
