Activate & Deactivate a License
Do you need to activate a license for a computer that is not connected to the internet? All you need is the computer key that you will get from the activation wizard (learn more here about offline activation). The same way works for deactivating a license (learn more here how to deactivate a license).

Get License Information

Email license keys
If you do not have your license key(s) at hand, you can retrieve a list of keys associated with your e-mail address.
