When I try to set up an Oracle odbc dsn, I get the following error "The setup routines for the INTERSOLV 3.00 32-BIT Oracle driver could not be loaded due to system error code 126". What does this error mean?

This error indicates that the Oracle Client is not installed on your computer. You can only use the Oracle odbc driver after you have installed the Oracle client. If you have the Oracle client installed and still get the error, you should ensure that the appropriate DLLs for the Oracle Net8 Client are in your environment path variable or in your Windows SYSTEM32 directory.
