Problem Description

I have installed a new MATLAB version, but running COMSOL with MATLAB keeps opening the older version of MATLAB.

Solution

You need to manually update the MATLAB root directory path.

In the COMSOL Desktop, go to the Options menu and select Preferences. In the Preferences window select LiveLink Connections. In the LiveLink™ for MATLAB® you can browse the new MATLAB installation folder. For Windows users, click the Register MATLAB® as COM Server button. Finally click OK and close the COMSOL Desktop.

Please verify the COMSOL Livelink for MATLAB system requirements to ensure the compatibility between the programs. See also: MATLAB function calls fail (kb 1093)
