Why do I get the error saying I need to install Coder products when they are already installed?

I'm encountering the error message below stating that I need to install Coder products, even though I already have MATLAB Coder, Simulink Coder, and Embedded Coder installed with valid licenses. How can I resolve this error and proceed with code generation?
MATLAB Coder, Simulink Coder and Embedded Coder products are required to generate code for this hardware board. Install the required products.

To troubleshoot this issue, first ensure that you have indeed MATLAB Coder, Simulink Coder, and Embedded Coder properly installed and licensed. You can refer to the following link for detailed instructions:

If all the Coder products are indeed installed and licensed correctly, it's possible that the code generation functionality is not enabled for your model. You can enable it by executing the following commands in MATLAB:
>> mdl = 'ModelName'; >> load_system(mdl); >> set_param(mdl,'UseSimulinkCoderFeatures','on') >> set_param(mdl,'UseEmbeddedCoderFeatures','on')
By enabling these features, you should be able to proceed with code generation successfully.
