Description

The Ado.NET driver is a DLL file. This DLL is registered in the GAC by the Ado.NET driver installer.
Your .NET application will use the following rules of precedence to find the DLL:

       (1)     Search the GAC (Global Assembly Cache)
       (2)     Search the codebase of app.config
       (3)     Search the applications path
       (4)     Search the privatePath of app.config

If you run the application on a computer on which you have not previously run the Ado.Net installer, the driver will not be present in the GAC, and so rules 2,3, and 4 will be used to find the DLL.

Environment

Ado.NET applications use the Ado.NET driver to connect to a TIBCO Data Virtualization server. This article discusses the rules of precedence that applications follow in order to find the driver on your system..
