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
Even I was this problem. The issue was the environment variable ERLANG_HOME=c:\Program Files\erl9.0 which was never existed.
I cross checked the path. The correct path was c:\Program Files\erl9.3.
After correcting the
ERLANG_HOME=c:\Program Files\erl9.3
the problem solved. So, definitely it is a path issue.
