PRB: Procedure Entry Point FDIV Not Located in MSVCRT20.DLL

 Last reviewed: May 23, 1997
Article ID: Q128148
The information in this article applies to:
  • Microsoft Visual C++, 32-bit Edition, version 2.1

SYMPTOMS

When you start a Visual C++ version 2.1 application on Windows NT, you may receive this error: 

   The procedure entry point 'symbol' could not be located in
   the dynamic library MSVCRT20.DLL.
where 'symbol' could be one or all of these: 

   _adjust_fdiv
   _adj_fdiv_r
   _adj_fdiv_m64
   _adj_fdivr_m64

CAUSE

The MSVCRT20.DLL file shipped with Visual C++ version 2.1 includes a fix for Pentium floating point functions. The faulty Pentium FDIV operations are implemented as internal functions in MSVCRT20.DLL. The error listed above is caused by linking to an older version of MSVCRT20.DLL - one that does not contain these functions.

RESOLUTION

The MSVCRT20.DLL library located in the WINDOWS\SYSTEM32 directory under Windows NT, should be version 2.10 or greater. You can check the version by using the File Manager. Select (highlight) the MSVCRT20.DLL file, and press ALT-ENTER to get its properties. If it isn't version 2.10, copy the newer version from the Visual C++ version 2.1 CD.

A patch has been made available for those who do not have the Visual C++ version 2.1 product CD. For additional information, please see the following article in the Microsoft Knowledge Base:
