SYMPTOMS
After installing or upgrading ODBC files, you receive one of the following error messages:

The ODBC resource DLL (c:\windows\system\odbcint.dll) is a different version than the ODBC driver manager (c:\windows\system\odbc32.dll).

-or-

The ODBC resource DLL (c:\windows\system\odbcint.dll) is a different version than the ODBC setup dll (c:\windows\system\odbccp32.dll).

-or-

The ODBC resource DLL c:\windows\system\odbcint.dll) is a different version than the administrator (c:\windows\system\odbcad32.dll).

The message may appear periodically on your screen or when you attempt to open the ODBC Administrator.



CAUSE
This error is usually caused by outdated or mismatched ODBC components. Many applications install ODBC, including Visual InterDev, Active Server Pages, Windows NT 4.0 Service Packs, and many others. During the installation of ODBC, a service or application may have been using one or more ODBC files. The files that were in use could not be overwritten, causing a version mismatch between the files that were in use and either the ODBC Driver Manager or the ODBC Administrator.

Because the ODBC 3.0 and 3.5 and later Driver Manager performs automatic version checking between itself and the other ODBC core components, it detects the version mismatch and generates the warning.



RESOLUTION
Download and install the latest version of the Microsoft Data Access Components (MDAC). This package updates all ODBC and the newer OLE DB drivers and resources on the system. The latest version of MDAC can be downloaded from the following Microsoft Web site:

NOTE: You cannot install MDAC separately in a Windows 2000 computer because MDAC is part of the system components.

You can also diagnose and reconfigure your current MDAC installation by using the Component Checker tool. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
