No. It doesn't consume it - it sets it. And if you end up setting
environment variables while installing then they are not available to
your installer or subprocesses launched from it until you broadcast a
WM_WININICHANGE message. See here:
for how we do it.

The rabbitmq-plugins.bat tool just edits the enabled_plugins file. This
is a plain text file containing an Erlang term which is a list of
explicitly enabled plugins. So you could deploy your own file containing
exactly "[rabbitmq_management]." (without the quote marks) and not have
to invoke the batch file at all.
If you are embedding RabbitMQ inside another product, you might find
that you want to skip using the installer and just install the various
components within your own installer. See
for some information on how you might do that.
