Matlab 2015a License File Crack

How to Find and Activate MATLAB R2015a License File

MATLAB is a popular software for numerical computing, data analysis, and visualization. MATLAB R2015a is an older version of MATLAB that was released in March 2015. If you have MATLAB R2015a installed on your computer, you may need to find and activate the license file to use it. In this article, we will show you how to do that.


What is a MATLAB License File?

A MATLAB license file is a text file that contains information about your MATLAB license, such as the license number, the expiration date, and the products you are authorized to use. The license file also contains a digital signature that verifies the authenticity of the license. The license file is required to run MATLAB on your computer.

Where Can I Find the MATLAB License File?

The location of your MATLAB license file depends on your license type and operating system. There are two main types of MATLAB licenses: individual and network. Individual licenses are tied to a specific user or computer, while network licenses are shared among multiple users or computers. The following table summarizes the common locations of the license file for different license types and operating systems:

License TypeOperating SystemLicense File Location


IndividualMacOS/Users/$USER/Library/Application Support/MathWorks/MATLAB/R2015a_licenses


Network (Designated Computer, Concurrent, Named User)WindowsC:\Program Files\MATLAB\R2015a\licenses

Network (Designated Computer, Concurrent, Named User)MacOS/Applications/

Network (Designated Computer, Concurrent, Named User)Linux$MATLABROOT/licenses

Note that the %AppData% folder in Windows and the Library folder in MacOS are hidden by default. You can access them by typing their paths in the address bar of the file explorer or the finder. The $USER variable represents your username, and the $MATLABROOT variable represents your MATLAB installation folder.

The license location can also be stored in an environment variable called LM_LICENSE_FILE or MLM_LICENSE_FILE. This is common for network licenses that use a license server. You can check or set these variables using the instructions in this [support article].

How Do I Activate the MATLAB License File?

To activate the MATLAB license file, you need to have an activation key and a file installation key. The activation key is a 25-character code that identifies your license and links it to your MathWorks account. The file installation key is a 32-character code that enables you to install MATLAB products. You can find these keys in your [MathWorks account] under My Products and Services.

To activate the MATLAB license file, follow these steps:

  • Launch the MATLAB activation client by selecting Activate MATLAB from the Start menu (Windows), or by running the script from the terminal (MacOS or Linux).

  • Select Log in with a MathWorks Account and enter your MathWorks account credentials.

  • Select the license you want to activate from the list of licenses associated with your account.

  • Enter the activation key for your license.

  • Select the installation folder for your MATLAB products.

  • Enter the file installation key for your products.

  • Confirm your activation information and click Activate.

  • Wait for the activation process to complete and click Finish.

  • Restart MATLAB if it was running during the activation.

You can also activate MATLAB without an internet connection by using a license file and an activation key. For more details, see this [support article].

Troubleshooting Tips

If you encounter any problems with finding or activating your MATLAB license file, here are some tips to help you:

  • Make sure you have the correct license file for your MATLAB version and license type. You can download the license file from your [MathWorks account] under My Products and Services.

  • Make sure you have the correct activation key and file installation key for your MATLAB products. You can find these keys in your [MathWorks account] under My Products and Services.

  • Make sure you have a valid and active MATLAB license. You can check the status of your license in your [MathWorks account] under My Products and Services.

  • Make sure you have an internet connection or a license server connection if you are using a network license. You can test your connection by opening a web browser and going to

  • Make sure you have the required permissions to access the license file location and the MATLAB installation folder. You may need to run the MATLAB activation client as an administrator (Windows) or use sudo (MacOS or Linux).

  • If you still have problems, contact [MathWorks support] for further assistance.
