same problem that colleagues have detected me.

I've tried all the variations. I tried it in safe mode. I used the pre-patched 0.9 version. It doesn't work. I don't know what else to try.

Perhaps the server check is just for validation. Once the license is validated, the application doesn't compare it again.
See the attached image. The key is identical, even though there are three different activations.

The check on Kaspersky's servers only occurs using the activation in the application itself, when KTL resets the information. When I use .lic/.dat files, activation is done by KTL and not by KIS.

Would you mind terribly, if you and gatorade approve, to share that .dat or .lic file with me as well?
I find myself in the same boat: KTA worked for KIS 21.3.10.391 wonderfully for a good two years until just yesterday, when after going through the regular motions I got the 'License Expired' after the restart, then gave it a couple more tries, also with KTL which is new to me, but no dice.

Also tried a licence reset .bat file for our KIS version from the threads here, but after that I only got 'Licence Missing' after trying to reset the trial, not entirely that shockingly... Anyway, got the license to 2025.11.14 from here somewhere (assuming the same person from whom you did, from the thread) and imported it with KTA, and now got 4 days, but dunno what to do after. Interestingly (or maybe not?), my license key is the very same as the one in your screenshot(s).
Also, had a (final) W10 update session before Microsoft pulled out, like yourself, figured why not - I'm just hoping it doesn't have anything to with this. I feel like I'm wholly unprepared for system restore points and registry hacking and whatnot, truth be told... xD

But I digress, would you be in a sharing mood, maybe? Pretty please with a cherry on top.
