How to clear the MATLAB Runtime (formerly MATLAB Runtime or MCR) cache?

1) Locate the MATLAB Runtime cache folder. On Windows, the typical path depends on the MATLAB Runtime version:

Before R2024b:

C:\Users\<username>\AppData\Local\Temp\<username>\mcrCacheX.Y

Since R2024b:

C:\Users\<username>\AppData\Local\MathWorks\MatlabRuntimeCache\RXXXXx

For more information on the default locations across platforms, see the MATLAB Runtime Component Cache documentation.

If MATLAB is available on the machine, you can determine the cache folder by running the following command in MATLAB:

>> mcrcachedir

.

2) Navigate to the parent directory (for example., C:\Users\<username>\AppData\Local\Temp\<username>\) and delete the relevant "mcrCacheX.Y" or "RXXXXx" folder used by your application.

If you are unsure which version is used, you may delete all "mcrCacheX.Y" or "RXXXXx" folders in this directory. This will clear the MATLAB Runtime cache. 

3) After deleting the cache folder(s), restart the application.
