How do I find my User Name in order to activate my license?

When I try to activate my license, it asks for my User Name. How do I find this?

Answer 1

[MathWorks Support Team]

To find your User Name, follow the instructions below for your operating system.

Windows

The fastest way to get your User Name is from a Windows Command Prompt:

• Locate the search field. On Windows 7 this is in the Start Menu, on Windows 8/8.1 this is on the Start Screen, and on Windows 10 this is in the Taskbar
• Enter "cmd" into the search field and type enter

In the Command Prompt, enter the following command:

set username

MacOS

To obtain your User Name, open a Terminal window:

• Open Finder
• Open the "Applications" folder
• Open the "Utilities" folder
• Start the "Terminal" application

In the Terminal window, enter the following command:

whoami

Linux

To obtain your User Name, open Terminal and run the following command:

whoami

The User Name can also be obtained by using the lmutil.exe utility included with the MATLAB installation. You can run the following commands to determine the User Name needed for activation:

Windows:

"C:\Program Files\MATLAB\R20XXx\etc\winXX\lmutil.exe" lmhostid -user
The User Name will be displayed as “USER=_<your_login_name>”

_

Mac:

/Applications/MATLAB_R20XXx.app/etc/maci64/lmutil lmhostid -user
The User Name will be displayed as “USER=_<your_login_name>”

_

Linux:

/usr/local/MATLAB/R2018b/etc/glnxa64/lmutil lmhostid -user
The User Name will be displayed as “USER=_<your_login_name>”
_
If access to the command window is not available, you can use the MATLAB activation client to determine what your Login Name is. To do this, you will need to first open the MATLAB activation client. The activation client can be found in the following locations:

Windows:

C:\Program Files\MATLAB\R20XXX\bin\win64\activate_matlab.exe.

Mac:

Use Finder to go to /Applications . From there, control-click (right click) on the icon for your MATLAB version, such as MATLAB_R2015b.app . In the menu, choose "Show package contents". In that directory, you will find an Activate.app.

Linux:

/usr/local/MATLAB/R2018a/bin/activate_matlab.sh

Once the activation client is open,

• Click on “_Activate Manually without the Internet” _and click next.
• Click on “_I do not have a license file. Help me with the next steps”_
• On this screen you will see your Login Name: “_Computer Login Name:<your_login_name>”_

I entered an incorrect login name. How do I correct it?

[Mohammed Nuwaid Nattukallingal]

Start -> MATLAB R2016b -> Activate MATLAB R2016b , Then redo the activation process again .

[Vaidyanathan S]

For MAC, open Finder, go to 'Applications', right-click on MATLAB*, and select 'Show Package contents'. Here, click on 'Activate' and follow the instructions.

[Javier Naranjo]

i do not understand the process of activation once i have entered a wrong user name

[Walter Roberson]

Javier, you should be able to just re-execute the activation sequence.

Go to "C:\Program Files\MATLAB\R20XXX\bin\win64\activate_matlab.exe." and use this program to do the activation process all over again.

[Lise Lynen]

When I go through the activation process all over again and add my license file, it never asks for the user name and says everything is activated.

When I try to launch Matlab however, it shows me the -9 error saying the username is incorrect. Can someone help me on this? How do I change the username? And why is it incorrect because I was never asked to input a username, I just added to path to my license file.

[Colin Fraser]

Lise,

If you added the path a license file, its possible that license file had an incorrect username set to it. You would need to reactivate again from the website with the correct username.

If you need further assistance, please contact MathWorks support:

if you are using Linux, avoid using "sudo ./matlab" to launch the application, instead just use "./matlab"

This answer is very helpful. I was unable to activate MatLab on my borrowed laptop. I kept typing "Student User" for my user name and MatLab kept yelling at me for being the wrong user. Tried "set username" and found that my ACTUAL user name was "Administrator". Tried that and it works!

This saved me, thank you!
