Hello everyone,
Today I installed Python, Jupyterlab, and jupyter-matlab-proxy through pip in the Windows command prompt. I also installed the newest version of Matlab today and I set it in the system path. Matlab itself works fine after inputting my license information.
I am able to create notebooks with Matlab kernels and Matlab scripts within Jupyterlab desktop. However, whenever I try to run the notebooks with the Matlab kernel, nothing happens. I have tested other notebooks and they work fine. If I try to open Matlab from within Jupyterlab desktop, instead of being prompted to enter license information, I get a 404 error.
I have uninstalled and reinstalled jupyter-matlab-proxy and it made no difference.
Anyone know something I might be missing? Please let me know, thank you.

I toyed around with it a little more and after removing Jupyterlab desktop, I was able to figure out all I had to do was install setuptools and restart matlab-proxy. Everything works as it should now. Thanks!
