DOCUMENT:Q148485 23-APR-1996 [winnt] TITLE :Service Pack 4 Causes Some Installation Programs To Fail PRODUCT :Microsoft Windows NT PROD/VER:3.51 OPER/SYS:WINDOWS KEYWORDS:kbsetup -------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.51 Service Pack 4 - Microsoft Windows NT Server version 3.51 Service Pack 4 -------------------------------------------------------------------------- SYMPTOMS ======== After you install Windows NT 3.51 Service Pack 4, if you attempt to install or upgrade any application that replaces Windows NT 3.51 files that are in use, the installation may fail. For example, when you attempt to install the Shell Technology Preview for Windows NT 3.51, the Setup fails and your computer no longer boots up. CAUSE ===== Windows NT 3.51 Service Pack 4 replaces SMSS.EXE. The Shell Technology Preview Setup and some third-party installation programs call the MoveFileEx(MOVEFILE_DELAY_UNTIL_REBOOT) API to replace some Windows NT system files during a Setup reboot. The Service Pack 4 SMSS.EXE does not properly replace the files during reboot. RESOLUTION ========== To correct this problem, apply the fix mentioned below. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 3.51 Service Pack 4. A fix to this problem is now available, but has not been regression-tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for more information.
