1.3 Authorization and Registration 9
• A valid email address
• Your product serial number (on the back of the sleeve of your CD or in your
confirmation email for downloads)
• The challenge key generated by the program
Note that it is possible to use the program during 15 days before completing
the authorization process. This period can be convenient if you are installing the
program on a computer which is not connected to the internet. After that period,
the program will not function unless it is supplied with a response key.
In the following sections we review the different steps required to generate the
challenge keys and obtain the response key. The procedure is similar on Windows
XP and Mac OS systems.
1.3.1 Step 1: Generating the challenge key
After launching the installer for the first time, a pop-up window will appear asking
you if you wish to authorize your product now or later. If you are ready to authorize
Ultra Analog Session now, click on the Next button otherwise click on the Autho-
rize Later button. If your computer is connected to the internet, we recommend
that you authorize your product now.
