title: Cannot install RabbitMQ UI plugin in fresh install
body: <p>I am trying to install RabbitMQ Management plugin in a fully fresh install of Erlang and RabbitMQ in Windows 7. I have installed Rabbit MQ. I can verify that the windows service is running. When trying to install the Management plugin I get this error:</p>
  
  <pre><code>C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.12\sbin&gt;rabbitmq-plugins enable rabbitmq-management
  </code></pre>

  <p>That is the message I am getting. I am new to Erlang and it doesn't makes sense at all.</p>
  
  <p>Any input will be appreciated.</p>
