SYMPTOMS
========

Near the end of the installation for Visual Studio 6.0 (or individual language
products), you may receive one of the following error messages:

  can not run unicode version of atl.dll on Win 95 please install the correct
  version

  -or-

  ACMSetup executed an invalid instruction in module ATL.DLL at 015f:5f3e303e

This error may also occur when you install Visual Studio 6.0 (or individual
language products) on Windows 95 or Windows 98.

CAUSE
=====

The cause of this error is a conflict between the version of Atl.dll on your
system and the version Visual Studio is trying to install.

RESOLUTION
==========

1. Search for "Atl.dll" (without the quotation marks).

2. Rename the version found in Windows\System as "Atl.123" (without the
  quotation marks).

3. Restart the system.

4. Install Visual Studio 6.0.

STATUS
======

This behavior is by design.

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

Restarting the computer may not be necessary but will insure updating of the
system cache.

Steps to Reproduce Behavior
---------------------------

Replace your version of Atl.dll with version 3.0.8168.0 - ATL Module for Windows
NT (Unicode).

NOTE: The Unicode and ANSI versions of this file have the same version number. By
renaming the existing Atl.dll on your system as Atl.123, you allow Setup to
install the version it requires.
