overwrite file in use dialog to always install/uninstall on restart

Hi,

Is there any way I can overwrite the file in use message box to always install or uninstall the file that is use at restart? I don't want the message of file in use to be displayed , but I want the option "Ignore" to be selected by default when the file is in use ( to always install/uninstall the file at restart and files that are in use). I was thinking to set the silent flag at INSTALL_STAGE_INSTALLING_FILES, and then set back to not silent on MSG_PROG_CREATING_UNINSTALL, will this work or is there any other way to not show the file in use notice dialog?

Thank you
