How can I delete the JRE that ships with MATLAB and replace it with my own?

I understand that MATLAB’s shipped version of the Java Runtime Environment (JRE) may depend on an outdated version of the MSVC library (msvcr100.dll). How can I delete the shipped version of the JRE and replace it with my own version?

Although MATLAB ships with a version of the JRE, MATLAB, users can replace it with a different version. For more information on which JRE version is supported for each release of MATLAB, see this page:

Step 1: Install and setup your version of the Java JRE

For step-by-step instructions, select the link below that corresponds to your OS.

• Windows
• Linux
• Mac

Note: Starting with R2021b, MATLAB users can call matlab_jenv to specify a custom JRE location.

Step 2: remove the Java JRE that is shipped with MATLAB

Delete the folder containing the JRE and the outdated MSVC library. MATLAB’s version of the shipped JRE is located in matlabroot/sys/java/jre, where the value of matlabroot for your installation can be determined with this MATLAB command

>> matlabroot

Delete the folder matlabroot/sys/java/jre.
