Error programming Arduino - Arduino IDE at Folder " is inaccessible or corrupt

Been having trouble with Arduino Engineering Kit.

Using MatLab version 2020a update 3.

Matlab knows that MKR 1000 is connected, but cannot program it.

Comes up with this error each time: Arduino IDE at Folder " is inaccessible or corrupt.

I have tried:

Reinstalling Matlab

Reinstalling Matlab Support Package for Arduino (multiple times) including following the clean install instructions found in previous support cases.

Uninstall and reinstall Arduinio IDE

Typing in arduinio.IDERoot "c://Program Files (x86)// Arduino";

All end up the same result.

I found out how to correct it. I uninstalled all the packages required for the A.E.Kit, and then did a clean install for each of them, in the correct order.

This resolved my problem, and I hope if others have this error it will fix their's too.

what is the correct order?

Answer 2

I followed the order as per the online instructions for the AE kit on Matlab.

Somehow, when I installed the first time, I got one out of order and it gave me a world of hurt. Simply uninstalling the packages did not work, I had to reinstall the entire program to get it to reinstall properly.
