Hi @MHofmann-rossmanith,

I recently encountered the same error message (Unrecognized option neighbours), although not on Windows 11. With the help of this comment I could solve it. I dont kow if you are familiar with the erlang.cookie, but Erlang under Windows is respecting HOMEDRIVE/HOMEPATH to look for this file. Installation failed for me when my home drive was not accessible. I changed the HOMEDRIVE/HOMEPATH environment variable in the registry under HKEY_CURRENT_USER\Volatile Environment to an accessible drive, and installation worked after that. I think this only needs to be done once when installing the service.
Maybe this can help in some way.

@MHofmann-rossmanith this is an odd error. Please open an administrative command prompt and run this command:

set > rabbitmq-server-6581.txt

Attach the generated file to your response. Then, can you please download this file:

https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.11.5/rabbitmq-server-windows-3.11.5.zip

...extract it, then, using an administrative command prompt, do the following:

cd path\to\rabbitmq_server-3.11.5
.\sbin\rabbitmq-server.bat

Please note if RabbitMQ starts correctly. If not, copy the output and attach it to your response. Then

.\sbin\rabbitmq-service.bat install

See if that command installs the service. Thanks
