Cause

When entering an activation code, you may see the hint "Invalid activation code". The error occurs if you have entered the activation code incorrectly.

Solution

To fix this problem:

• Check if you have entered the code correctly. Please note that capital Latin letters I, O, L are not used in our activation codes.
• Check if you have entered all 20 characters of the activation code.
• If you are using an automatic keyboard layout switcher, disable it for a while before entering the code. 

Cause

The Incorrect activation code error may occur when you try activating the application with the activation code that you have just bought. The information about your code may be submitted to the Kaspersky Lab activation server with a delay. 

Solution

Please allow some time for the activation code to become valid. Try to activate the application again in 24 hours.
