After installing MATLAB 2024a, I get the following warnings and errors after startup

Warning: Initializing Java preferences failed in matlabrc.

This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was:

MATLAB:dispatcher:loadLibrary

C:\Program Files\MATLAB\R2024a\bin\win64\mcr.dll

Error using ismcc

You should contact Tech Support.

There are several options. The one you want is Installation and Setup although I don’t see that particular issue listed in the options, so contact MathWorks directly. Include the URL of this thread in your note to them so that you don’t have to repeat everything you listed here.

Thanks for the responses. I deleted the installation, and trashed all matlab folders, then re-installed. This eliminated the issue.
