Why I am seeing these message when uninstalling R2021b version?
" C:\Program Files\MATLAB\R2021b\help\simulink\helpsearch\segments_1c (The system cannot find the file specified) "
The problem started when I tried to update the R2021b version but a problem occured and the update is corrupted and then i couldn't run matlab anymore so I downloaded the R2022b version it is working but i nedd to uninstall the older version.

Manually delete the folder “R2021b” inside of “C:\Program Files\MATLAB\”. If you want to re-install afterwards, you should be able to with the folder removed.

Thanks for this revealing experiment. This was not the case in the version I had to re-install. "Select an empty folder" clarifies clearly, that your suggestion is important for solving the problem.

Not a problem. I admittedly didn’t look at the installer’s log files, but I imagine they give more insight as to what file(s) specifically prevent the usage of the folder for installation and why the installer doesn’t like what is present.

If the installation is corrupted, the uninstallation can fail. Then install this version again overwriting the existing installation folder and uninstall it afterwards.
[EDITED] Consider Jestzer's suggestion to delete the installation folder in modern Matlab versions.

Simply run the installer again. Did you use the default folder to install in, then do this again. But if you have chosen a specific folder to install in, choose this folder again. Afterwards the installtion is complete and the uninstalling will run successfully.
