Activating a new license and deactivating the older one

Hi,

In my company we have purchased one license. Due to some reasons that license lasted only one month and we have purchased a new license now. We tried to deactivate the old license from Help -> Licensing -> Deactivate Software but every time we click on De-activate button the window hangs and the cursor keeps rolling.

Is there any other way of deactivating the old license ? Or is there something wrong in the process we are following ? Or do we need to uninstall the software and upon installation again , enter the new license file ?

Visit https://www.mathworks.com/mwaccount/?s_tid=user_nav_myac . Click on the line corresponding to the license in question. Click on the Install and Activate tab of the page that comes up. A list of activated computers will come up, each with its own Computer Label. To the far right of the computer label list there is a Deactivate button.

Hi Walter,

The issue is that the license in question, "41289048" is not coming up in the list of installed licenses. However, on the desktop (as shown in the previous image), it is still displayed as an active license.

Additionally, in the license directory

C:\Program Files\MATLAB\R2025b\licenses,

the only license file present is associated with license ID 41289048.

We would like to completely remove all references to this old license from the system.

In the My Software list, click on 41289048. On the page that comes up, click on Install and Activate. That should bring up the list of activated computers.

An exception would be if the license is a "Networked" license. Those kinds of licenses are "borrowed" each time the user requests for them. Information for dealing with those kinds of licenses is at https://www.mathworks.com/help/install/license/key-administrative-tasks.html . However, we can see from the list that the license in question is an "Individual" license rather than a networked license.
