TITLE   :Service Pack 4 Causes Some Installation Programs To Fail
PRODUCT :Microsoft Windows NT
PROD/VER::3.51 SP4,4.0
OPER/SYS:
KEYWORDS:kbsetup

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Workstation versions 3.51 SP4, 4.0 
 - Microsoft Windows NT Server version 3.51 SP4 
-------------------------------------------------------------------------------


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. This problem was corrected in the latest Windows NT 3.51 U.S. Service
Pack. For information on obtaining the Service Pack, query on the following word
