MATLAB Installation Guide for Windows

License File

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 each product. The license manager grants or denies access to a product depending on the availability of the license keys associated with each product.

The MathWorks includes information in your License File that identifies the system on which you intend to run the license manager. You had to identify this system, your license server, when you made your purchase. The MathWorks needs the host ID of your license server when it creates your License File. See Finding the Host ID on a Windows System for more information.

Figure 2-1 is 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. The lines that begin with a pound sign (#) are comments. The license server identification information (host ID or Internet address) is included as a comment in the License File. A backslash character at the end of a line indicates that the line continues onto the next line. (For more detailed information about License Files, see License Management.)

Creating Your License File

You must create a License File from the license e-mail you received from The MathWorks. Open a text file using a text editor, such as Notepad, and copy the section of the message marked by the BEGIN and END lines into a text file. Name the file license.dat and store it in a temporary directory, such as C:\TEMP. Make sure you save the file as a plain text file and that the text editor does not add a .txt file extension to the filename.

If you received your license information in a fax, you must create a License File. Open a text file, using a text editor, and type in the license information exactly as it appears in the fax. Take care to preserve all spaces and line breaks.

Note    The MathWorks recommends that you do not edit your licensing information. Any changes you make can invalidate your License File.

Obtaining or Changing Your Licenses 

If you need to

• Obtain a License File
• Transfer a license to another CPU
• Combine licenses
• Move toolboxes from one license to another
• Change a license registration
• Update your contact information

go to the MathWorks Web site at www.mathworks.com and click Contact Us. Under Support and Service, select Customer Service Request and click the Web icon.

If you do not have Web access, you can contact The MathWorks via:

• E-mail at service@mathworks.com.
• Telephone at 508-647-7000, ask for Customer Service. To find the phone number of one of our international offices, go to the MathWorks Web site at www.mathworks.com and click Contact Us at the top of the page.
• Fax at 508-647-7001.

Depending on what you want to do, please have ready, or include in your e-mail or fax, the following items:

• Your e-mail address (if you have one).
• Your MATLAB Access number. MATLAB Access membership is free of charge and available to all customers. The primary contact on each license is automatically enrolled in MATLAB Access. The contacts receive their Access number via e-mail.
• Your License Number:
• If you have not previously installed MATLAB at your site, you can find your License Number on the upper right corner of the packing slip. Customers outside North America can obtain this information from their local MathWorks representative.
• If you are updating an existing MATLAB installation and MATLAB is running, type license or ver at the MATLAB prompt, or look in your existing license.dat file.
• The host ID of the server on which you will run the license manager.

Finding the Host ID on a Windows System

On Windows systems, you use the Ethernet address or IP address as the host ID. To get this information, open a command prompt window and run this command.

• C:\WINNT\system32\ipconfig /all
  

Note    Be sure to provide the host ID of the system on which you plan to run FLEXlm, not the host ID of a client workstation.
