Where are the license files for MATLAB located?

I would like to know where MATLAB license files are located.

Answer 1

[MathWorks Support Team]

The location of your license file(s) depends on your license type and operating system.

The license location can also be stored in an environment variable. This is common for network licenses. For more information, please see the following support article:

What are the LM_LICENSE_FILE and MLM_LICENSE_FILE environment variables and how do I set or check for them?

Windows: Designated Computer, Concurrent, and Network Named User licenses

License files are stored in the "licenses" folder within the MATLAB installation folder.

If MATLAB is installed in the default location, license files are stored here:

C:\Program Files\MATLAB\R20XXx\licenses

(NOTE: Replace "R20XXx" with release number, e.g. R2015b.)

Windows: Individual licenses

License files are stored here:

%AppData%\MathWorks\MATLAB\R20XXx_licenses

(NOTE: Replace "R20XXx" with release number, e.g. R2015b.)

The %AppData% folder is hidden by default.

To get there, open the Start Menu, enter %AppData% in the search box, and press enter.

It can also be located at:

C:\Users\%USERNAME%\AppData\Roaming

macOS: Designated Computer, Concurrent, and Network Named User licenses

License files are stored inside the MATLAB application package.

Right click, CTRL-click, or two-finger click on the MATLAB icon in your Applications folder and select "Show Package Contents."

In the folder that opens up, open the "licenses" folder to see your license files.

macOS: Individual licenses

License files are stored in the Application Support directory. Click on the Finder icon in your dock (the blue face) and go to the "Go" menu in the menu bar. Select "Go to Folder " and enter this:

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

where $USER is the username you use to login to your computer. In the folder that opens up, your license files are stored in the "R20XXx_licenses" folder, where R20XXx is the release of MATLAB you are using, e.g. R2017a.

If you are using a MATLAB version older then R2016b, your license files are located in a different directory. Instead, navigate to:

~/.matlab

and then enter the appropriate R20XXx_licenses folder.

Linux: Designated Computer, Concurrent, and Network Named User licenses

The license files are stored in the MATLAB installation directory:

$MATLAB/licenses

If MATLAB is installed in the default location, license files are stored here:

/usr/local/MATLAB/R20XXx/licenses

(NOTE: Replace "R20XXx" with release number, e.g. R2015b.)

Linux: Individual licenses

License files are stored in the ".matlab" folder within your home folder:

~/.matlab

In the .matlab folder, license files are stored in separate folders for each release:

R20XXx_licenses

(NOTE: Replace "R20XXx" with release number, e.g. R2015b.)

I found the folders, but there are .lic files instead of .dat files. Are they the same?

[Darsana Thulasi]

Any file with the extension .lic are actually license files.

[doctor]

It's the same.

[Walter Roberson]

Note as of R2016b, on OS-X, the license files are at

~/Library/Application\ Support/MathWorks/MATLAB/

in the appropriate R20*_licenses directory.

[Dhananjay Kumar]

Windows: Individual licenses

find them at:

C:\Users\USERNAME\AppData\Roaming\MathWorks\MATLAB\R20XXx_licenses

[Alex Dharini]

In my linux system, I cannot find R2019b_licenses at .matlab .

[Colin Fraser]

Check to see if it is in /usr/local/MATLAB/R20XXx/licenses

I'm trying to install R2019a on a NASA laptop that cannot be connected to the internet.

I go to a different Windows 10 computer and download matlab_R019a_win64. I transfer this file

to my Windows 10 laptop and run it. I get an option to manually install a license file in order to activate.

I go back to the internet and get a matlab license file license.lic following instructions. I get no

other information.

I place this license file in the %AppData% location on my laptop

I press Finish.

The menu goes away and nothing happens. I can find no trace of R2019a on my laptop.

Question: What should I REALLY do to install R2019a on my NASA laptop.

By the way

my name is Stephen Schery

my matlab license number is [SL: removed license number]

we have paid for current year support.

Thanks

Stephen Schery

[SL: removed email address]

[Steven Lord]

Hello Stephen,

When you extracted the installer to a directory, that directory should contain a PDF file titled install_guide.pdf or something similar. Those are the instructions for how to install MATLAB. In the first chapter of that guide there are instructions that walk you through installing MATLAB with a File Installation Key and activating an installation without using the Internet.

If while performing any of the steps in those instructions you encounter a problem, please contact Technical Support directly using the telephone icon in the upper-right corner of this page. Installation Support can help you complete the installation.

BTW, I've removed the license number and email address from your answer. Removing your license number may help avoid others trying to use your license, and removing your email address may (possibly) help avoid spammers harvesting your address.
