An activation code (or response code) is the code you use to activate your Mac-based CineForm software.  This Code is generated using your Name, Serial Number, and the challenge request code from the system you are using.  The code is unique to that system only.

On Macs with Mail enabled, the process is automated. Follow the steps here: Mac Product Activation.

On Macs without Mail enabled, submit the form at www.cineform.com/activate.aspx. Then an Activation Code will be sent to you.
