Export Standalone FMU with External C++ Code is not working

I tryed to implement the example: Export Standalone FMU with External C++ Code from the MathWorks page:https://de.mathworks.com/help/slcompiler/gs/export-standalon-fmu-with-external-cplusplus-code.html

even though I got the modell runing in Matlab I can not export it as an FMU. I get the following Massage:

Can anybody help me?

I encountered a similar error while following the provided documentation.

The error message indicates that MATLAB is unable to locate FMUExportWithExternalCPP.dll in its path, preventing the creation of the harness model. The current example uses the command:

exportToFMU('FMUExportWithExternalCPP', 'FMIVersion', '2.0', 'FMUType', 'CS', 'CreateModelAfterGeneratingFMU','on');

I would suggest removing the argument CreateModelAfterGeneratingFMU and manually create the harness model instead.

exportToFMU('FMUExportWithExternalCPP', 'FMIVersion', '2.0', 'FMUType', 'CS');

A possible cause for this issue might be that the system's "PATH" environment variable does not include the path to the MATLAB libraries from the specific release used for exporting the FMU, or that another version's path takes precedence. Please ensure that the path "C:\Program Files\MATLAB\<your MATLAB release>\bin\win64" (or its equivalent for your setup) is added to the environment variable and prioritized above paths for other MATLAB versions. This should help in locating the correct libraries.
