Insert the Tassman program disc into your CD-ROM drive. Launch Explorer to view the content
of the CD-ROM and double-click on the installer file to launch the installer.
If you purchased this software online, simply double-click on the installer file that you have
downloaded and follow the instructions of the installer.
1.3 Authorization and Registration
The Tassman uses a proprietary challenge/response copy protection system which requires autho-
rization of the product. A challenge key is a long string of capital letters and numbers that is
generated uniquely for each machine during the registration process. In other words, for each
machine you install this program on, a different challenge key will be generated by the program.
The response key is another unique string of capital letters and numbers generated from the data
encrypted in the challenge key. In order to obtain a response key, you will need to connect to the
A|A|S website and provide the following information:
• 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 Tassman now, click on the
Next button otherwise click on the Authorize Later button. If your computer is connected to the
internet, we recommend that you authorize your product now.
When you click on the Next button, a second window appears asking you to enter your serial
number. Type your serial number as it appears on the back of the sleeve of the Tassman CD-ROM.
If you purchased Tassman online, an email with your serial number will have been sent to you at
the address which you provided during the purchase process.
After entering your serial number, click on the Next button and your challenge key will appear
automatically in the next pop-up window.
