How can I roll back from Matlab2021b Update4 to Update3?

I have installed Matlab 2021b update4 but I require the update 3 version. How can I roll back to update 3?

Why do you need update 3? Is there a specific bug that was fixed in update 4 where you need the uncorrect behavior?

For releases I can understand why you need a specific version, but for updates I don't see how an older update could be better (unless update 4 would contain a bug itself).

Hello Sara,

You connot rollback an update once installed.

You will need to delete the MATLAB installation and reinstall the MATLAB version and update as necessary.

Please download the ISO image of required MATLAB Update as linked in this answer : How do I download a MATLAB ISO archive? - MATLAB Answers - MATLAB Central (mathworks.com)

Thanks.
