MUI - Customizing the Cancel prompt

Hi,

I've got a installer using MUI and when you click on the Cancel button, the following prompt is displayed:

Are you sure you want to quit <<Name>> Setup?

where <<Name>> is what I've set using the "Name" command.

How can I customize this prompt to display an alternative string?

Kind regards,
Dave.
