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

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

SYMPTOMS
========

When you try to install 32-bit programs using InstallShield (Setup.exe),
InstallShield may stop responding (hang).

CAUSE
=====

This behavior can occur when the Microsoft Windows NT 4.0 virtual DOS machine
(VDM) files are corrupted.

RESOLUTION
==========

To resolve this behavior, rename the following files by using the .old file name
extension at a command prompt, expand the original files from your Windows NT
4.0 CD-ROM, and then reapply the latest Windows NT 4.0 service pack:
