TITLE   :BUG: Setup Program Created by PDW Disables Windows 95/98 System
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:6.0
OPER/SYS:WINDOWS
KEYWORDS:

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

 - Microsoft Visual Basic Learning, Professional, and Enterprise Editions
   for Windows, version 6.0
   on the following platforms: Win95, Win98
---------------------------------------------------------------------

SYMPTOMS
========

The Package and Deployment Wizard (PDW) is used to create a standard
installation program for a program created in Visual Basic 6.0. The client
system is running Windows 95 and contains two hard drive partitions. The
first hard drive partition contains the operating system files while the
second hard drive partition contains the TEMP folder and the installation
program.

When you run the installation program from the second hard drive partition,
the following Setup Error message box appears:

   "Setup cannot continue because some system files are out of date on your
   system. Click OK if you would like setup to update these files for you
   now. You will need to restart Windows before you can run Setup again.
   Click Cancel to exit setup without updating system files."

After you click OK, one of the following occurs:

1. The system restarts but does not completely install the program. When
   you run the setup program, the following error message appears:

      A required .DLL file, C:\Windows\System\OLEAUT32.DLL was not found.

2. During the Start Up process, the following error message appears:

      Windows could not upgrade one or more system files.

      You cannot start the system after seeing this message.

   NOTE: This bug only occurs on systems with the following attributes:

      - The system is running Windows 95 or Windows 98.

      - The system contains at least two hard disk partitions.

      - The system folder and the TEMP folder reside on different
        partitions.

CAUSE
=====

The following files were removed from the System folder and not updated
because the Windows\System and Temp folders reside on different hard drive
partitions:

 - ASYCFILT.DLL
 - COMCAT.DLL
 - MSVBVM60.DLL
 - MSVCRT40.DLL
 - OLEAUT32.DLL
 - OLEPRO32.DLL
 - STDOLE2.TLB

These files are updated during reboot via a mechanism built into Windows 95
and Windows 98.

RESOLUTION
==========

1. Make sure the Windows\System and Temp folders are on the same drive.

2. If this bug has already occurred, you need to copy the following files
   to the System directory and restart Windows.

    - ASYCFILT.DLL
    - COMCAT.DLL
    - MSVBVM60.DLL
    - MSVCRT40.DLL
    - OLEAUT32.DLL
    - OLEPRO32.DLL
    - STDOLE2.TLB

   These files are included in your Visual Basic distribution disks or
   you can download the following file from the Microsoft Software Library:

       ~ vb6sys.exe

   This self-extracting executable file contains the files required by
   the System directory. After you run the self-extracting executable file,
   copy the expanded files to your system directory and restart Windows.

   For more information about downloading files from the Microsoft Software
   Library, please see the following article in the Microsoft Knowledge
   Base:

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article.

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

When you run an installation program created by the Package and Deployment
Wizard (PDW), the installation copies files to the TEMP directory. As part
of the installation process, the installation program checks the versions
of the previously mentioned files stored in the system directory.

If those files in the System directory are older than the files copied to
the TEMP directory, the installation program causes Windows to restart and
to replace the older files in the System directory with the newer files
from the TEMP directory during the restart.

If these files are updated, Windows must be restarted.

While Windows is restarting, it first deletes the files in the System
folder then attempts to replace them with the files in the TEMP folder. If
the System and TEMP folders are on different hard drive partitions, the
deletion succeeds but the replacement fails; the older version files are
deleted from the System directory but the newer version files are not
copied to the System folder.
