How do I activate my Microsoft Office programs?
The Activation Wizard automatically contacts the Microsoft licensing servers through your Internet connection. If you are using a valid Product Key that has not already been used for the allowed number of installations, your product is activated immediately. When you activate through the Internet, your product ID (derived from the installation Product Key) is sent to Microsoft through an encrypted transfer. A response (the confirmation ID) is sent back to your computer to activate your product. If you choose to activate your product through the Internet and you are not already connected, the wizard alerts you that there is no connection.
