title: Unable to launch rabbitmq management console in Windows
body: <p>On a Windows 7 Enterprise 64 Bit OS, I installed Erlang (otp_win64_20.0.exe) and RabbitMQ 3.6.9 (64bit) as standalone one. I have set System Variable for ERLANG_HOME. The installation was successful and RabbitMQ service is running. </p>
  
  <p>But when I trying to enable rabbitmq_management, I am getting following error.</p>
  
  <pre><code>C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.9\sbin&gt;rabbitmq-plugins.bat enable rabbitmq_management
  Plugin configuration unchanged.

     Changes will take effect at broker restart.
