MATLAB Support Package for Arduino Hardware does not install correctly

I have installed the Arduino Support Package, but when I try to run

a = arduino()

I get the error

arduino requires MATLAB Support Package for Arduino Hardware.

When I click on the link, it tells me that the package is installed. A similar error occurs when I try to run

arduinoExplorer

I am unable to uninstall the package (it uninstalls for a long time).

Hi @Andrew,

Sometimes, MATLAB might not automatically add the support package folders to its path. To fix this, try running the following command in MATLAB:

restoredefaultpath; rehash toolboxcache

If you are having trouble uninstalling the package, you can remove it manually. Also, please make sure that you are installing and using the support package with the same version of MATLAB.

For a step-by-step guide on installing the support package, you can follow the instructions in these documentations:

Hope this helps!
