My license has changed and needs to be updated. How do I update my MATLAB license file for an Individual or Designated Computer license?

Answer 1

[MathWorks Support Team]

If you are able to launch MATLAB

To update your license manually from within MATLAB, perform the following steps:

1. On the MATLAB toolstrip in Resources, click the down arrow under Help.

2. Click Licensing.

3. Select Update Current Licenses...and follow the prompts to update your license.

If you are unable to launch MATLAB

If your license file has expired or there is another license reason preventing MATLAB from starting, you can update your license by launching the MATLAB activation client.

For instructions on launching the activation client, see Activate an Installation Online.

If you cannot connect to the Internet

If the computer that is running MATLAB cannot connect to the internet, you can download a license file manually from www.mathworks.com on an internet-connected computer and copy the license file to the offline computer.

1. Sign into www.mathworks.com.

2. Click your profile picture in the top right and then select My Account.

3. Select your license number from the list.

4. Click the *Install and Activate *tab.

5. On the right-hand side, under Related Tasks, select Activate to Retrieve License File.

6. Fill out all required fields and follow prompts. Click Continue.

7. At Next Steps, click Download License File.

8. Skip Step 2 *and click *Done.

9. Copy the license file to the licenses folder on the offline machine. The following support article contains instructions for finding license file folders on various operating systems:

Where are the license files for MATLAB located?

10. Start MATLAB. If you encounter difficulties, contact Customer Support.

Thank you for the response. I am using Matlab R2012b under OS X. The instructions above describe going to "Help->Licensing->Update Current License" but no such options exist under the Help menu. Are there separate instructions for updating the license under OS X?

[Chethan Pandarinath]

FYI, one method to do this in OS X is to go to the Applications folder, ctrl-click on MATLAB_R*.app, and select "Show Package Contents", then run the "Activate.app" application.

Chethan,

I think you may have been looking at the OS X Menu bar instead of MATLAB's toolstrip. When running MATLAB on OS X, there are actually two help menus on your screen. There is the standard Help menu in the OS X menu bar, and then there is the MATLAB Help menu in MATLAB's toolstrip. The licensing submenu is located in the MATLAB Help menu, which is marked in the toolstrip by a white circle with a black question mark inside of it.

Thanks worked for me

[Shuting Li]

I have download MATLAB 2020b, I have copied the lecense file into C:\Users\李书婷\AppData\Roaming\MathWorks\MATLAB\R2020b_licenses, but it still needs me activate again and again, and I cannot start MATLAB.

[Prasanna Mhapsekar]

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

There are two Matlab help areas. One is the small circle in the upper right next to the search documentation box. That's not it. The other is Home (tab) > Resources (section on the far right) > Help > Licensing > Update current license. Just wanted to be more specific because you can find Licensing info with the other help button. It just won't let you update your license.

Thank you!

[Sirou Chen]

thanks!!!

[he tin]

Thank you very much!

[Eric Lamonsoff]

Perfect! Thanks for the info.

[Muhammad Sujak MK]

it really works!!! Thanks a lot!

For license updates

How often can you update the license in Matlab?

My current license expires in 57 days, when license is updated will that one last for 57 days as well?

Answer 4

[Nicolas Wongso]

Also is this license update going to be free?

[Shawn Lyons]

Nicolas,

It sounds like you may be a user of an annually-renewed license. If your organization will be updating the license, you will need to contact them about any related costs. If you are a university student using an academic headcount license, it is likely that the update will be free, but again, you should contact your university to check their policy on license updates.

For further clarification, feel free to contact MathWorks Support and we can discuss the license update process.

How do I update my license file on a computer with no internet?

Answer 6

[abdulelah shewoil]

from where can I get the File Installation Key ??

Answer 7

[Sriram Narayanan]

That tool doesn't let me load in a new Concurrent License file (ie. to point the client at a new server, or if the server name changed). When I run it - still connected to the old server - it says "update not required".

It seems that the only way to get the client to load a new concurrent license configuration is to run the installer.

[Michael Laumen]

Just move (or delete) the license files (located under C:\Program Files\MATLAB\R20XXx\licenses ) first.

After restarting Matlab it will show the "Activate License"-dialog, where you can activate your license.
