Yes. It's a bit fiddly though.

You'll need to install at least one of the versions manually, the .exe 
installer assumes there's only one installation on the machine:

http://www.rabbitmq.com/install-windows-manual.html

You'll need to set various environment variables to separate the two:

http://www.rabbitmq.com/configure.html
http://www.rabbitmq.com/relocate.html

I would think you'd need at least RABBITMQ_BASE, RABBITMQ_NODE_PORT, 
RABBITMQ_NODENAME, RABBITMQ_PLUGINS_DIR and RABBITMQ_PLUGINS_EXPAND_DIR. 
Also RABBITMQ_SERVICENAME if you want to install both as services.

At least 2.8.6 and 3.3.4 use different ports for the management plugin 
by default, so you don't have to reconfigure that.
