Depending on your configuration, uninstallation may or may not require a password. If a password is required, ensure that you share the password only to users that will run the uninstallation program and then change the password immediately if it has been divulged to other users.
The password can be set or disabled at Administration > Global Settings > Desktop/Server tab > Security Agent Uninstallation Password.
The Security Server notifies the user of the uninstallation progress and completion. The user does not need to restart the client to complete the uninstallation.
In the event this procedure fails, see Using the SA Uninstall Tool.
