Change buttons for File Exists dialog?

[commhorizons]

I know that I can change the message displayed when a file exists and cannot be overwritten by calling
SetupData.SetLocalizedString("MSG_FILE_EXISTS_RETR Y").

However is it possible to change the dialog buttons from from MB_RETRYCANCEL to something else, such as MB_YESNO?

Thanks.

This is, as far as I know, currently not possible. The MessageBox type is defined internally in Setup Factory and cannot be customized.
