Running the Desktop Authority installation while a version of Desktop Authority is already installed will give you the ability to upgrade Desktop Authority or to uninstall it.
There are two different upgrade paths you can take.
Choosing the Express Upgrade option will skip the typical installation dialogs, confirm prerequisites and go directly to the Review dialog. You will, however, be given the opportunity to back up the databases.
Choosing the Custom Upgrade option allows you to proceed through the installation dialogs with permission to modify existing settings.
The Uninstall process is a two step process. The first part will remove all Desktop Authority files from the necessary servers. This process also configures a GPO that will remove all client side services. Since not all client computers are available at all times, the removal process via the GPO on client computers may take a few days to complete.
At a later date, once you are comfortable that the client side services have been removed from all of your client computers, run the Uninstall a second time to remove the DA GPO and remaining pieces.
