Never copy or install another version of cwbodbc.dll unless directed to do so by an IBM i Support representative. The cwbodbc.dll has dependencies on many other IBM i Access for Windows dlls. The version of the DLL must match the IBM i Access for Windows service pack. The installation directory is dependent on the version and release and the version of Microsoft Windows (32-bit versus 64-bit). The file is registered with the ODBC administrator during the installation.
The ODBC driver is delivered in the file C:\Windows\System32\cwbodbc.dll. The replacement for that product is IBM i Access Client Solutions and the Windows Application Package. Note that IBM i Access for Windows v710 was withdrawn from support in 2019. The ODBC driver is a part of IBM i Access for Windows or the IBM i Access Client Solutions - Windows Application Package and can only be installed with one of those two software packages.
