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.

Microsoft Dynamics AX 2012

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.

On the Start menu, point to All Programs, point to Administrative Tools, and then click Microsoft Dynamics AX Management Shell.
At the Windows PowerShell command prompt, PS C:\>, type the following command, and then press ENTER.

At the command prompt, type the following command, and then press ENTER.
