For those who have Kaspersky Total Security, Kaspersky Plus, or other versions, and end up with Kaspersky Premium after the automatic key addition, it's because you are NOT FOLLOWING the tutorials correctly. This issue only occurs when you mix up license keys during the first attempt.
So yes, that's what you did—but you're not realizing your mistake and are instead flooding the thread with incorrect test reports.
In your case, completely uninstall Kaspersky and reinstall it.
Then, re-activate your Kaspersky using option 3, as the registration file is corrupted due to your initial error.
Now, perform a "Trial reset" without adding any "Serial" key, and afterward, use option 2 to enter the serial number corresponding to your specific Kaspersky version.
The only thing actually being tested here is the trial period duration—which I cannot verify since I don’t have this issue myself.
All other problems mentioned in the thread are simply due to user errors.
Please follow the tutorials exactly, step by step.
Thank you 🙂
