You get the following error when connecting to a database.

Specified driver could not be loaded due to system error 126

This error occurs when some DLL files either are missing or are not in your machine PATH when connecting to a database. Note that many databases require a client side library installed and configured on the machine before any client can connect.

You do not need any client DLLs if you are using the "Wire Protocol" driver with WinSQL.

For example. There are several ODBC drivers available to connect to Oracle. The table below lists them.
