Cannot upgrade MATLAB from 2021a to 2021b.

I am trying to upgrade MATLAB to the last version (2021b) without uninstalling the current version (2021a).

When I check for new updates, it shows that the latest version is already installed, and it does not show that 2021b is available. I don't want to uninstall this version and download the newer one because I have a lot of installed toolboxes that I don't want to lose.

The screenshot below shows the problem.

This "Update" refers to the small patches or bug fixes in the same release, in your example, Release 2021a.

Install R2021b separately. There are no problem to have multiple releases installed on the same computer.

Do I have to install the toolboxes again for the other release?

Yes. Treat R2021a and R2021b as two software
