How to Uninstall and Reinstall RabbitMQ

You may encounter an issue when attempting to start RabbitMQ service. In certain instances this will require an uninstall and reinstall of Rabbit MQ (by reinstalling the Prism server).

This process should be followed only if you are instructed to do so by the Retail Pro technical support team.

Uninstall RabbitMQ

1. Make Tech Toolkit (TTK) backup
2. Turn off ECM and any other scheduled activities
3. Back out all workstations on the server
4. Back up \confs, \WebClient, and \Modules in the programdata\Retailpro folder
