Many users assume entering a license key is enough—but Kaspersky now relies heavily on account-based activation. That means your subscription is tied to your login, not just your code.

If your app still shows “trial” or “not activated,” it usually means one thing:
👉 Your license hasn’t synced with the correct account yet.
