The following error occurs when trying to access an ODBC data source from a 32-bit application under Win32s:
Attempt to load required component ODBC32.DLL failed.
There are two main causes for this:
Ensure that the ODBC setup program from the WIN32S\ODBC directory has been executed.
Additionally, after installing from the Visual C++ version 2.1 CD, you'll need to copy the ODBC3216.DLL file located in the WIN32S\ODBC directory (this is the correct thunking ODBC driver manager for Win32s) to the WINDOWS\SYSTEM directory and rename it to ODBC32.DLL to replace the incorrect ODBC32.DLL.
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was corrected in Microsoft Visual C++, 32-bit Edition, versions 2.2.
