Hi @ASIF ALI,

You are getting the warning since the directory "C:\OPAL-RT\RT-LAB\2024.1\common\bin" is added to the MATLAB Search Path but MATLAB cannot find the directory on your system. You'll need to remove this directory from the MATLAB Search Path to get rid of this warning.

Here are the steps to remove the directory from the search path:

1. Go to the "Home" tab of the tool ribbon,
2. Click the SetPath icon.
3. Then locate the missing folder and highlight it.
4. Click Remove, Save, and Close.

After performing the above steps, the warning should go away the next time you start MATLAB.

Please refer to the following resources for more information:

• MATLAB Search Path documentation - https://www.mathworks.com/help/releases/R2021b/matlab/matlab_env/what-is-the-matlab-search-path.html
• Changing Folders on Search Path - https://www.mathworks.com/help/releases/R2021b/matlab/matlab_env/add-remove-or-reorder-folders-on-the-search-path.html

Hope this helps!

In my experience, dead links in the path file aren't actually loaded when they fail at startup, so they won't even show up when you use the pathtool. You have to edit the actual file directly.

At least that's my experience.
