Finding the license key will depend on how the product was purchased and if it was registered; if the product was registered online, log in to the account that was made when the product was purchased and it will be located in the Manage CD Keys tab. The Manage CD Keys is located under the Manage My Products page in menu on the left-hand side.
If the product has not been registered but was purchased online, the activation key can be located in the confirmation email that was sent to the email provided when purchasing the product. For a product that was purchased in a retail store, the activation key should be located on the case or sleeve of the CD. If none of the above methods work, log in to the account made during the purchasing process, then fill out and turn in a form for technical support asking for a replacement activation key.
