Installation of Mathematica requires that you complete the license registration. In the following, we explain the procedure for registration at the time of installation. Alternatively you can register your license after installation, but we don't explain here.

1. Start Windows, and insert the Mathematica CD-ROM. The following window will appear.
   Click the icon "Install Mathematica to hard disk".

   

   If this window is not displayed, open the CD-ROM drive in Windows Explorer, and double click the icon shown below to display the install screen.

   

   In this example, the CD-ROM drive is "D:\".

2. For the Mathematica install type, select Single machine.

   

3. Next, you are requested to input user information. Fill the mandatory fields.

   Name: Your name
   Affiliation: Your affiliation
   License number: The number on the CD-ROM case

   

4. The following screen will be displayed. A machine-specific ID is shown in the MathID field.
   Register the ID at the Mathematica website to receive a password, which will be sent to you by email later.

   Select Web(W) to open your web browser, and you will be connected to the Mathematica web site.

   

5. When the following page will be displayed, fill the necessary items.

   Mathematica version: 4.2
   MathID for single user: Input the MathID and machine name as shown in step 4.

   If you are requesting more than one password, fill in the fields as shown in the example below.

   

6. At the Mathematica site registration page shown below,  register the name and the mail address of you (or who manage your Mathematica license). The password will be sent to the email address registered here.

   

7. 無事、登録されたことが表示されます。あとはパスワードが送られてくるのを待ちます。A message is displayed to show that your registration is complete. Wait a moment until your password arrives by e-mail.

   

8. Below is an example of e-mail notification with password.
   This contains:
   1. Machine name
   2. MathID
   3. License number
   4. Password
   Input the password in the email into the password field shown in step 4. You will not be able to use Mathematica without this password.

   

9. To confirm the expiration date of the license, start Mathematica, and click Help > About Mathematica.

   

10. The expiration date of license will be shown as follows.
