Silent Uninstall with Pre-Uninstall Dialog?

Greetings,

I am an end-user of a product that was installed using Setup factory.

I am trying to remotely uninstall the product using the uninstaller and the xml file but the developper added a dialog requesting an OK which apparently does not work with the silent switch.

Is there a way for me to override the dialog and just get on with uninstalling via Command Line?

Alernatively is there an uninstaller I could use to pipe the xml file through?

Thanks in advance,
Steven
