You can manually add an activation code to your account to synchronize the license information across your connected devices.
To activate your app through My Kaspersky:
If the code is added successfully, a corresponding panel appears in the Licenses section. Your apps that are compatible with the license and connected to your account will be activated. Additionally, a check is performed if the registered license should be sent to your connected devices manually. If so, you can select devices and send the license right away.
An activation code must be valid (the license cannot be expired) and must not be banned, blocked or already added. You can add no more than 100 activation codes to your My Kaspersky account.
