Article: Q169037
Product(s): Microsoft Windows NT
Version(s): WinNT:4.0

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

- Microsoft Windows NT Workstation version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

During an unattended installation of Windows NT 4.0 with the Win31upgrade=
option set to 1, Windows NT 4.0 may still prompt you with the following dialog
box:

  Setup has found a previous version of Microsoft Windows in the directory you
  have chosen for installing Microsoft Windows NT. Setup recommends installing
  into this directory since Microsoft Windows NT can interoperate with the
  previous version of Windows.

- To install Windows NT in the same directory, press ENTER.

- To select a different directory for Windows NT, press ESC.

This dialog box should only appear if the Win31upgrade= entry is set to 0.

CAUSE
=====

This problem can occur if the path statement in the Autoexec.bat does not
contain an entry for the directory that is being upgraded.

RESOLUTION
==========

Make sure the directory that is being upgraded is included in the path statement
in the Autoexec.bat file of the boot drive.

MORE INFORMATION
================

During an unattended installation with the Win31upgrade=1 switch set, setup
parses the Autoexec.bat file for the path environment variable. This parsing
occurs after the first restart and if the path entry does not contain a valid
path to the Windows directory that is being upgraded, the above condition
occurs.
