Invalid license key or activation code

Answer:

The message occurs during manual license key activation. The program determines that the activation code is not valid. This can be a result of a number of reasons:

1. The license key is mistyped. Please check the license key carefully and try again.
2. The activation code is mistyped. Please check the letter and digit sequence carefully and try again.
3. The computer used to generate the activation code is different than the one we are trying to activate the key on. If this is the case, please deactivate the license key or obtain a new key.
