Note: Each product license is intended for use by a single named user, a real person using their first name, last name, and email address, for the duration of the subscription term. The person using a license must match the person assigned to that license when purchasing or renewing a subscription. Single named-user licenses cannot be transferred to another user, but can be updated at specific times.
