BUG: Mismatched USER32.DBG File on Windows NT 3.51 CD-ROM Disc

The information in this article applies to:

• The SETUPDBG.EXE utility included with: Microsoft Visual C++, 32-bit Edition, versions 2.0, 2.1, 2.2, 4.0, 4.1

SYMPTOMS

When you install Visual C++, Setup creates an icon for the SETUPDBG.EXE utility called "NT System Symbols Setup." On running this utility to install the Windows NT symbol files (.DBG files), you are prompted to enter the full path to your Windows NT distribution files. If you specify a path to the Windows NT 3.51 CD-ROM drive, you encounter this message.

   The version of the file 'USER32.DBG' does not match the
   corresponding dll on your machine. Do you want to copy it?

CAUSE

The Windows NT 3.51 CD-ROM compact disc contains an incorrect version of the USER32.DBG file.

RESOLUTION

You can debug applications with Visual C++ without this file installed. However, the Visual C++ debugger will not be able to determine the context of functions located in USER32.DLL.

The USER32.DBG file included in the Win32 Software Development Kit (SDK) is correct, so installing the Windows NT symbol files (.DBG files) from the Win32 SDK CD-ROM compact disc will work correctly. You can also copy this file directly from the Win32 SDK into your \WINDOWS\SYMBOLS\DLL directory.

Alternatively, you can obtain the same correct USER32.DBG file by downloading USER32.EXE from the Microsoft Software Library.

You can download USER32.EXE, a self-extracting file, from the Microsoft Software Library (MSL) on the following services:

• Microsoft Download Service (MSDL)

        Dial (206) 936-6735 to connect to MSDL
        Download USER32.EXE (size: 225767 bytes) 
  

• Internet (anonymous FTP)

        ftp ftp.microsoft.com
        Change to SOFTLIB\MSLFILES directory
        Get USER32.EXE (size: 225767 bytes) 
  

STATUS

Microsoft has confirmed this to be a bug with the Windows NT 3.51 CD-ROM compact disc. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
