I had one relaese of MATLAB R2022b installed on my system but it is missing the optimtool. Then I treid to install R2017a, it is not working. Instrad it gives me the license error. Further when I uninstall the 2nd one, then the system gives me the message " Deactivate the license. If you deactivate the license, all releases will not work on this system". How to solve this issue?

Hi Sadiq,
As I understand, you are getting license errors including a “Deactivation required” error when trying to use multiple releases of MATLAB simultaneously.
The "Deactivation required" message seems to indicate that the license file is invalid or expired. More details on this error can be found in the following MATLAB Answers post:

When installing multiple releases of MATLAB, be sure to select a separate installation directory for each release, as different versions must be installed separately. Providing the specific license error received on trying to install R2017a would help in debugging the issue further.
Hope this is helpful!
