I am trying to connect to an Access 2000 database, but I keep getting error number 3706 (Provider cannot be found. It may not be properly installed).

I have a reference to ActiveX Data Objects 2.5 Library, I am using "Provider=Microsoft.Jet.OLEDB.4.0" in the connection string, and I have the Jet Driver (version 4.00.6200.00) installed.

Does anyone know why I would get this error and what the solution might be?
