Unable to resolve MEX file incompatibility issue

Hello,
I am a newbie at using MATLAB and am facing some trivial dificulties in following the calibration steps. Hope you could help.

Found the following links online with similar incompatible mix issue:

• https://www.mathworks.com/matlabcentral/answers/26633-invalid-mex-file-invalid-win32-application
• https://www.mathworks.com/help/matlab/matlab_external/version-compatibility.html

One solution mentioned is to use the original version of MATLAB. Could you share what it was?

When I check system config:
system('arch') = Win64

• Why does auto_calib look for Win32 application?
• How to resolve this?

Thanks,
