TITLE   :PRB: Wrong Mfc40.dll and Msvcrt40.dll from ActiveX CD-ROM Disc
PRODUCT :Microsoft C Compiler
PROD/VER:4.1 4.2
OPER/SYS:
KEYWORDS:kbsetup kbtshoot kbGenInfo kbVC kbArtTypeINF

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

 - Microsoft Visual C++, version 4.1 
 - Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2 
 - Microsoft Visual C++, 32-bit Professional Edition, version 4.2 
-------------------------------------------------------------------------------

SYMPTOMS
========

Some applications written using Visual C++ 4.1 or 4.2 may break as a result of
installing the beta version of the ActiveX Development Kit.

CAUSE
=====

When you run setup (Setupsdk.exe) from the \Msdnsmpl\Tools\Inetsdk\ directory of
the Internet SDK on the beta version of the ActiveX Development Kit, the CD-ROM
installs the Visual C++ version 4.0 Mfc40.dll and Msvcrt40.dll. These overwrite
any newer versions of these files that may already be installed, so they may
break some applications already built with Visual C++ 4.1 or 4.2.

The size, version and date of the wrong version files installed in the
Windows\System directory are:

   Mfc40.dll     923,408 bytes  Ver. 4.0.5277  date 4/3/96
   Msvcrt40.dll  312,832 bytes  Ver. 4.00.5270 date 4/3/96

You can check these file properties from Windows NT File Manager or Windows 95
Explorer.

The Readme.txt file in the \Msdnsmpl\Tools\Inetsdk\Inetsdk\ directory of the beta
ActiveX Developmant Kit CD-ROM has a date of 4/3/96 and file size of 16,649
bytes. Later versions of ActiveX Development Kit will have a later date and
different size for this file.

The correct size and version of the files in Visual C++ version 4.1 are:

   Mfc40.dll     921,872 bytes  Ver. 4.1.6038
   Msvcrt40.dll  326,656 bytes  Ver. 4.10.6038

The correct size and version of the files in Visual C++ version 4.2 are:

   Mfc40.dll     921,872 bytes  Ver. 4.1.6038
   Msvcrt40.dll   65,024 bytes  Ver. 4.2000.6164

RESOLUTION
==========

To correct the problem, copy these two files from the \Redist directory of the
Visual C++ 32-bit Edition CD-ROM to the Windows 95 \System directory (or Windows
NT \System32), or, download and install the latest version of ActiveX INETSDK
which is available from the following Web site:

NOTE: This article does not apply to Visual C++ versions 5.x and above.
