rabbitmq-plugins.bat enable rabbitmq_management - django

Question

I install Erl7.3 and rabbitmq-server 3.6.2. I using Win7 32bit. After installing when I run 'rabbitmq-server' command it gives:
ERROR: node with name "rabbit" already running on "admin-PC"
When I run 'net stop RabbitMQ && net start RabbitMQ' it stopped RabbitMQ service and restarted successfully.
After that When I run "rabbitmq-plugins enable rabbitmq_management", it gives following errors and nothing is shown at http://localhost:15672:
Plugin configuration unchanged.
Applying plugin configuration to rabbit#admin-PC... failed.
Error: {undef,[{crypto,module_info,[attributes],[]},

{rabbit,start_apps,1,[{file,"src/rabbit.erl"},{line,451}]},
{rabbit_plugins,ensure,1,
[{file,"src/rabbit_plugins.erl"},{line,52}]}]}
For your information, I set environmental variables as:
'Variable name: ERLANG_HOME', 'Variable value: C:\Program Files\erl7.3';
'Variable name: RABBITMQ_SERVER', 'Variable value: C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.2'
and system path "%ERLANG_HOME%;;%RABBITMQ_SERVER%\sbin"
How to resolve this errors?

rabbitmq management plugin needs the cryptopakage to work.
see:
Error: {undef,[{crypto,module_info,[attributes],[]},
{rabbit_misc,module_attributes,1,
Try to use the Erlang 18.3 version.
EDIT
After installing when I run 'rabbitmq-server' command it gives:
ERROR: node with name "rabbit" already running on "admin-PC"
This is normal since rabbitmq-server starts the server, but you have rabbitmq installed and running as windows service.
And you should use the 64 bit version
