If you need to install ARA 2.0.1 on a system that currently has ARA 2.1 installed, it is necessary to use the ARA 2.0.1 Installer to do a custom remove of the software prior to installing ARA 2.0.1. Failure to do so may result in the message "no description" when attempting to open the ARA control panel or error -43 when trying to connect.
