•    Abort in Abort/Retry situations.
•    Cancel in Retry/Cancel situations.
•    Yes (=continue) in a           DiskSpaceWarning/DirExists/DirDoesntExist/NoUninstallWarning/ExitSetupMessage/ConfirmUninstall situation.

These message boxes are not suppressible:
•    The About Setup message box.
•    The Exit Setup? message box.

​

/CLOSEAPPLICATIONS
Instructs Setup to close applications that use files that need to be updated by Setup, if possible.
