Error when running SimMechanics model on Arduino Mega 2560

Hello, I am trying to run a Simmechanics model on an Arduino Mega 2560 however I get the following error message:

The call to realtime_make_rtw_hook, during the after_make hook generated the following error: The specified file "C:\Program Files\MATLAB\R2013a\toolbox\physmod\mech\lib\win64\mech" does not exist on the path.

After looking at my MATLAB toolbox path I found that the "mech" folder is under the "lib" directory instead of "win64". I have tried moving the folder but it seems to move it back when restarting MATLAB. Does anyone know how to fix this issue?

Thanks!

EDIT I was able to move the mech folder under the win64 directory but now get the following error:

Error in 'SM_0001_000S_FULL/GROUND1/RootGround': Initialization commands cannot be evaluated.

Caused by: Error in 'SM_0001_000S_FULL/GROUND1/RootGround/_mech_engine': Initialization commands cannot be evaluated.

Internal Error: A primary message table for module 74 was already registered with a differing collection of error messages.

My comment may get removed but there is a way to use the arduino input to control movement of your solidworks model by using Labview instead of simmechanics. I say this just to help those who are in deep frustration like me.
