I get the following error after installing the VEX Companion app in MATLAB R2018b and trying to open it from the app menu.

This is a known issue with version 16.2.2.0 of the VEX Companion app when installed in MATLAB 2018b. In order to resolve the issue execute the following commands in the MATLAB command prompt or run the attached file:

>>vexpath=which('VEXCompanion','-all');
>>vexpath=replace(vexpath,'VEXCompanion.m','');
>>vexpath=fullfile(vexpath,'resources');
>>addpath(vexpath{1});
>>savepath
