Personal License Passwords (PLPs) and License Files

When you purchase one of the network license options, The MathWorks sends you licensing information in an e-mail or fax. This licensing information varies depending on your license option, but can include a Personal License Password (PLP) and a License File.

Personal License Passwords (PLPs)

A PLP is a series of five-digit numbers prefixed with a two-digit code, such as 17-12345-12345-12345-12345-12345, that identifies the products that you are licensed to install. Do not confuse your PLP with your License Number.

License Files

A License File is a specially formatted ASCII text file that contains encrypted product passcodes for each product you are licensed to run. Each product passcode identifies the number of keys available for that product. The license manager grants or denies access to a product depending on the availability of the license keys associated with each product. MATLAB client installations use the License File to determine how to connect to the license server.

The following figure presents a sample of a License File sent by The MathWorks. Each line in the License File that begins with the keyword INCREMENT identifies a product you purchased. Each INCREMENT line identifies the product, the number of keys available for the product, and other information. (The INCREMENT lines in your License File might not include every element shown in the example.) The backslash (\) character indicates that the line continues onto the next line.

The lines that begin with a pound sign (#) are comments. The MathWorks Installer uses the information in these comment lines (license server host ID or Internet address) when it processes the License File during installation.

Creating a License File

You must create a License File from the licensing information you received in your license passcode e-mail message from The MathWorks. Follow these instructions:

  1. Open a text file, using any ASCII text editor.

  2. In the license passcode e-mail message, select all the information from the BEGIN line to the END line. Make sure to select all the information contained in this section, including the comment lines.

  3. Copy the license information from the e-mail message and paste it into the open text file.

    In general, do not edit the licensing information; you may invalidate a license. However, note the following:

    INCREMENT Identification_Toolbox MLM 17 01-sep-2007 1 \
       EC5C175AGG025G2AD73A DUP_GROUP=UH SN=12345

    If you received your license passcodes in a fax, create the License File by typing in the license passcode information exactly as it appears in the fax.

  4. Save the file as a plain ASCII text file, naming it license.dat, and store it in any convenient folder.
