Prior to 6u14 we could not send a ping for cancellation of the .msi file download because the user had not agreed to the license yet.

With 6u14 the dialogs were re-ordered so the user has already accepted the license agreement when they get to the download files dialog. In this case, we want to know when users cancel the download, so a ping should be sent when the cancel button is clicked, with a new return code that will indicate this cancellation.
