After entering in the activation details, you must restart 'System Preferences' before the activation takes effect.

The one automatically obtained by the keymaker should be correct for the system the keymaker is running on. The 'Product Key' required for registering and activating in o ffline mode is system specific. Once completed, there aren't any other online checks where details are sent back to servers. Note: You must either disconnect from the Internet or block outbound connections for 'System Preferences' to get into offline activation mode.
