Microsoft Open Database Connectivity 2.1

This article was previously published under Q126607

SYMPTOMS

If the Open Database Connectivity (ODBC) version 2.1 Software Development Kit (SDK) from the January Microsoft Developer's Network (MSDN) Level 2 CD is installed on a system that already has Microsoft Visual C++ version 2.1 installed and you attempt to run Visual C++ components, it fails with the following message:

MFCCLSWZ.DLL This required file cannot be loaded. Please reinstall the Microsoft Visual C++ development environment.

CAUSE

The ODBC 2.1 SDK Setup from the January MSDN Level 2 CD replaces the Visual C++ version of the files MSVCRT20.DLL and CTL3D32.DLL with older versions. The problem does not occur with any other versions of the ODBC 2.1 SDK.

RESOLUTION

Either reinstall Visual C++ 2.1, or copy the files MSVCRT20.DLL and CTL3D32.DLLl from the Visual C++ CD to the ODBCSDK\REDIST32 and WINNT\SYSTEM32 directories.
