Activation process

Product activation is a technical measure that helps protect Adobe against unauthorized use and copying of its software. Activation runs in the background and occurs whenever the application detects an Internet connection.

During installation, this product and your computer create an activation number. This number, along with the product serial number, is provided to Adobe during the activation process. This product can tolerate changes to your computer's configuration.

Minor reconfiguration of your hardware after the activation doesn't require an additional activation. If you replace or overhaul your hard drive, or if you remove this product from one licensed computer and install it on another, reactivate this product.
