Hi Mark,
When you encounter issues with installing a new MATLAB trial license because the system indicates you already have the items installed, you typically don't need to wait for the current license to expire to update or change your license. Here are steps you can follow to update your MATLAB license without waiting for the current one to expire:
- Deactivate the Current License: You might need to deactivate your current trial license first. Here is the documentation link for the same: https://www.mathworks.com/help/install/ug/deactivate-an-installation.html
- Activate the New License: After deactivating the current license, you can proceed to activate your new trial license. Here is the documentation link for the same: https://www.mathworks.com/help/install/ug/activate-matlab-installation-manually.html
I hope this helps!
