What version of FlexNet License Manager is necessary ro run MATLAB R2022a

I NEED LICENSE FOR MATLAB R2022a

[Walter Roberson]

If someone else paid for your license then contact them to get the license code. If you paid for your license then contact Mathworks Support for installation assistance. If no one has paid for a licence then someone will have to pay for it before you can use MATLAB.

You can download License Manager binaries from here. As of R2022a, FlexNet 11.18.1 is used.

We are looking to upgrade to R2022a. Will FlexNet 11.16.2.1 work with that version of Matlab?

[Kojiro Saito]

You can try replacing a license file to R2022a with existing FlexNet.

How do I update the license file used by the license manager?

But, R2022a is officially supported with FlexNet 11.18.1, so updating FlexNet is better.

How do I update the Network License Manager?

[Walter Roberson]

No, 11.16 will not work.

Mathworks updates flexera releases under two conditions:

• security fixes; Or
• access to new Features

When the existing Flexera is working, Mathworks does not bother to update requirements.

The third-level upgrades such as 11.16.1 to 11.16.2 do not always include Feature updates, so a change in the third component would potentially be compatible.

However, changes in the second component, 11.16 to 11.17 always include changes to Features. MATLAB needed a Feature update a couple of releases ago. 11.16 to 11.18 compatibility is not going to be possible.

Even in the case where your particular licenses do not need changes to Features, MATLAB will insist on the new version, to prevent the possibility of failures that depend on the exact flow (which toolboxes get invoked.)

This is very helpful information. Thanks to both of you!
