Unable to get CADI server port number


I'm a beginner in using DS-5 and to be familiar with that tool, I have downloaded and installed DS-5 Community Edition, version 5.19.0.

After installation, I started using the Fixed Virtual Platforms available on the package in order to start exercising on my laptop, so without real hardware indeed. I'm just following available user guide, but  "Launch and connect to specific model" step failed, with the error message reported in subject.


Have you got any clues for me?

Thanks in advance.

Best Regards,
