What does the license_info.xml file look like for new licensing technology and where should it be saved?

Answer 1

[MathWorks Support Team]

You may need to confirm that your license_info.xml is formatted correctly and in the correct folder for new licensing technology. It needs to be in your device's license folder and formatted in a certain way. We'll first check to make sure that it is in the correct folder and once we have, we'll confirm its contents are correct.

Please note that this may not entirely resolve the issue(s) you may be having, it simply ensures that you have this file in correct place and formatted correctly.

Section 1 - Location Confirmation

Windows

1. Go to the folder where you have MATLAB installed. If you don't know where this is, it is usually "C:\Program Files\MATLAB\R20XXx". The "X"s will need to be replaced with your release of MATLAB. For example, if you are using R2022b, you'd replace R20XXx with R2022b.
2. Go into the licenses folder. If you don't see a licenses folder, you may create one with the name "licenses" without quotation marks.
3. You should see a file labeled "license_info.xml" inside of this folder. Proceed to "Section 2 - Further Location Confirmation" regardless of whether you do or do not.

MacOS

1. Open Finder
2. Go to the folder where you have MATLAB installed. If you don't know where this is, it is usually your Applications folder.
3. Find your MATLAB release. Right-click or control-click on the app and then select "Show Package Contents".
4. Go into the licenses folder. If you don't see a licenses folder, you may create one with the name "licenses" without quotation marks.
5. You should see a file labeled "license_info.xml" inside of this folder. Proceed to "Section 2 - Further Location Confirmation" regardless of whether you do or do not.

Linux

1. Go to the folder where you have MATLAB installed. If you don't know where this is, it is usually "/usr/local/MATLAB/R20XXx". The "X"s will need to be replaced with your release of MATLAB. For example, if you are using R2022b, you'd replace R20XXx with R2022b.
2. Go into the licenses folder. If you don't see a licenses folder, you may create one with the name "licenses" without quotation marks.
3. You should see a file labeled "license_info.xml" inside of this folder. Proceed to "Section 2 - Further Location Confirmation" regardless of whether you do or do not.

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>

All Operating Systems

If you have lost your license_info.xml or couldn't find it in any folders mentioned above, you can create a new file named "license_info.xml" and save it with the content from Section 3. You should save it in the licenses folder from Section 1.
