Whats the Problem when downloading Code from Simulink to Arduino Mega 2560?

Hello there im using MatLab R217a and Windows 10. I have the following problem: i wanted to use the Arduino mega2560 for an easy Task but before i wanted to Test it with a simple Model (LED on Port 24). Now when i start to generate the Code, it looks fine first, but at the End there comes the following Error. Here is the Point, where the Problem is i think. I hope someone can help me.The last quote is Part of the first One

    C:/ProgramData/MATLAB/SupportPackages/R2017a/toolbox/target/supportpackages/arduinobase/src/MW_digitalio.cpp

Can you locate this file on your machine?

Find "rtwtypes.h" and copy in this folder C:\ProgramData\MATLAB\SupportPackages\R2018a\toolbox\target\supportpackages\arduinobase\include then maybe need do the same for "MW_target_hardware_resources.h" and "multiword_types.h" this work for me, hope this work for you to.

What a manual hack. there must be a real solution than copying around files.
