"Directory name is invalid." etc. with rabbitmq-plugins on Windows

Based off of the comment @LukeBakken made in the original question, I was able to get around this by creating a local admin user and doing the install under the local admin user. This was after hours of battling by setting the HOMEDRIVE, etc.

Seems that the Order at which the commands are ran Matters, this worked for me, shuffle them around

SET HOMEDRIVE=C:
rabbitmq-plugins.bat enable rabbitmq_management
rabbitmq-service.bat stop
rabbitmq-service.bat install
rabbitmq-service.bat start

I solved this by following way : 1. Opened command prompt using administrative mode 2. Go to sbin directory. Execute command "SET HOMEDRIVE=C:"
