I\'m ask/answering this question because it hung me up & it\'s likely someone else will have the same problem.
Install of RabbitMQ x64 v2.8.6 on Windows Server 2
1- Set environment variable:
Variable name : ERLANG_HOME Variable value: C:\Program Files (x86)\erl6.4
ERLANG_HOME
C:\Program Files (x86)\erl6.4
note: don't include bin on above step.
2- Add %ERLANG_HOME%\bin to the PATH environmental variable:
%ERLANG_HOME%\bin
PATH
Variable name : PATH Variable value: %ERLANG_HOME%\bin
This works well.
