Works Like a Charm Thanks I want to retain the Repair Installation in text mode so [unattended] and OemPreinstall is out of the question to copy SFX to %systemdrive% During GUI Setup I wanted to extract a password protected SFX at roughly the same time as Product Key, User, Computer Name etc(T-39 to T-33). Then bugger off and let my RunonceEx Install Reboot etc. No stupid questions to halt the install. Job Done I can finally run my sfx off the CD Rom from Detachedprogram Thanks
