Hi Kevin,
You can create a custom uninstall script. If this specific 3rd-party application comes with an .exe uninstall then simply call that from within your uninstall script. If it was a .msi install then simply execute the appropriate uninstall procedure from your uninstall .sbi.
If there is no uninstall for the 3rd-party install at all then simply execute the necessary steps to remove the components. For example, stop a service and uninstall the service itself and the file(s), etc.
Does this help?
