2.3.3 Entering a Password in the Front End

In order to run Mathematica, you must have a mathpass file containing a valid password. This file is created automatically when you enter a password in the front end. The front end presents you with a password dialog box whenever you try to run Mathematica without a valid license. This can happen in any of the following situations.

  • You have installed Mathematica but have not yet entered a password.

  • The mathpass file has been moved or modified.

  • The license server specified in the mathpass file cannot be found on the network.

  • The license server is on the network, but MathLM is not running.

  • The license server is on the network, but all passwords are already in use.

When you enter a password during the installation process, a mathpass file is automatically created and saved in the $InstallationDirectory\Configuration\Licensing folder. However, if you do not have permission to write to this directory, the mathpass file is saved in the $UserBaseDirectory\Configuration\Licensing folder.

Once the front end password dialog box appears, you have the option of entering either a single-machine password or a network password. A network password is the name or IP address of a license server on which MathLM is running.

To enter a network password via the front end:

1. Launch Mathematica. The front end password dialog box appears.

2. Click the radio button marked Network License. Enter the name or IP address of the MathLM license server in the space provided.

3. Click OK.

To enter a single-machine password via the front end:

1. Launch Mathematica. The front end password dialog box appears.

2. Click the radio button marked Single Machine. Then enter the license number in the space provided. Your license number is printed on the license certificate that came in the box. You can also enter your name and the name of your organization. Click OK when you are done.

3. The following dialog box appears showing the MathID number for your machine. You will need to contact Wolfram Research and supply this MathID and your license number to obtain a password (see Section 1.4.2 for details).

4. Enter your password in the text box provided, then click OK. Mathematica launches and is ready for use.
