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

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.

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?

Also is this license update going to be free?

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.

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.

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.
