Where is mathematica license file

If you have a line in the mathpass file that has an upcoming expiration date and Mathematica uses that line to launch, Mathematica will issue a warning message about the license expiration, even though other lines that do not have upcoming expiration dates may be available. After the expiration date for a line passes, Mathematica will ignore that line when launching.

If you have already updated your mathpass file with a line that does not have an upcoming expiration date, feel free to ignore any expiration notices Mathematica displays. These messages will stop appearing after the expiration date passes.

If you wish to remove the expiration notices immediately, edit the mathpass file to remove the lines with the upcoming expiration date, or move them to the bottom of the file. Midway through the installation process, a MathID number will be displayed on your screen. This MathID number is a machine-specific identification number that is automatically determined when running the installer on a machine.

In addition to your MathID number, you will need to provide the activation key located on your electronic or printed license certificate. Once you have your MathID number, you can register and get a password by following the instructions in "Activating Mathematica". Be sure to write down the password and keep it for future reference. The MathID number for your machine can change under certain circumstances, for example, if you reformat your hard disk. Passwords are stored within a file called mathpass.

The location of the mathpass file for the Wolfram System varies by operating system. See "Configuration Files" for mathpass file locations. The mathpass file is created automatically by the installer, but you may find it necessary to edit the file by hand at times.

The mathpass file may contain one or many password entries, depending on your license type. Blank Blank. Blank Details. Article ID: Recipient s - separate email addresses with a comma. Check out this article I found in the Client Portal knowledge base.
