How to adjust Java heap space while updating license file? Can't open MATLAB to increase heap space

I'm on Windows 10, currently have MATLAB 2018a (Student edition) and am currently trying to update my license file with a R2022b installer (also for students).

It's not working because I get the error 'Java heap space' and MATLAB closes/crashes. See below for screencapture.

I have looked this problem up and it requires you to increase Java heap space. However, the steps require you to open MATLAB first--this is clearly not something I can do because I'm stuck at step one.

What recourse do I have? Is there a way to adjust Java heap space from outside the application with a configuration file or something?

Thanks in advance for the help--I need MATLAB for my studies.

Hi,

I understand that you are not able to open MATLAB itself, for increasing your java heap space.

You can refer to this MATLAB Answer: Change Java Heap Memory Settings Without Starting Matlab? - MATLAB Answers - MATLAB Central (mathworks.com)

Hope this helps!
