How do I uninstall Avatax for Microsoft Dynamics AX Connector?

Overview

You are upgrading to a new version of the AvaTax for AX connector, and want to know the best way to uninstall the old connector.

Environment

Microsoft Dynamics AX 2012

Resolution

  • The first step to uninstalling Avalara Avatax for Dynamics AX is to run the uninstall wizard from inside AX. To do that please go to Avatax> Setup> > Uninstall.  Then follow the instruction on the form.
  • Go to each AOS where Avalara Avatax is installed (and possibly the SQL server) and remove the local piece by going to Control Panel > Programs and Features> Avalara Avatax for Dynamics AX> Uninstall. That will unregister the existing Avatax dll file.

    

  • Final step is to uninstall the model file from our AX environment. Perform the action in all AOS.
