Start HMI V5.6 locally does not work with Windows11

[ZagelHeiko]

With Windows10 the HMI starts normally, but with Windows11 it does not continue after opening the "mosquitto.exe".

At Bosch Germany, Windows 11 has only very recently entered the early adopter phase and wasn't available previously. We will investigate the problem as soon as we have the chance to reproduce it in a Windows 11 development environment.

I found a workaround for that. Execute Std\Hmi_V5_8\MQTT\mosquitto.exe before you Run HMI locally. It works for me.

That's good news! At least we have a simple workaround now.

For everyone as background information: Mosquitto is an MQTT broker that is used for communication between the main HMI process and the 3D Navigation (=VirtualAssist) process. The HMI checks at startup if Mosquitto is already running and starts it otherwise. And that's the point where something goes wrong on Windows 11. If Mosquitto was already running, the HMI won't start it and also won't stop it when it is closed.

So, if you are working on Windows 11, you can just start Mosquitto once in the beginning and always leave it open.

Of course, we will investigate why it doesn't work on Windows 11 asap, but I am glad this workaround should enable everyone to work with the HMI on the development computer.

For our projects I rename the MQQT folder so that is not started. With running MQQT we had many hangs on some systems.
