rabbitmq-server silent run displays message box with error and hang installation

[tkarpli]

Describe the bug

If the setup is run in silent mode and, for some reason, the RabbitMQ service fails to start, a message box is displayed. This causes the installation to hang until a user manually closes the dialog.

This defeats the purpose of silent mode. Moreover, a person integrating this setup command into other systems running in the background would not expect such behavior

Workaround:
Run the setup with /S /NOSERVICERUN, and then manually start the service using rabbitmq-service start. This approach correctly returns an error code without showing any message boxes.

Reproduction steps

See #13846
...

Expected behavior

Running rabbitmq-server in silent mode should return an appropriate error code from the process without displaying any message boxes or requiring any user interaction.

More information is needed:

• What Windows version and patch level are you using?
• Why didn't the service start in your environment?

I see that you just added the workaround that I would have suggested. For now, users can do that - do not indicate that the service should be started.

If you would like to investigate how to change the installer's behavior if the service fails to start, the source code is available here:

https://github.com/rabbitmq/rabbitmq-packaging/blob/main/windows-exe/rabbitmq_nsi.in

The NSIS installer product is used.
