Looking for Microsoft OLE DB Provider for Oracle


I'm working with Visual Studio 2003 .NET.
I'm having problems trying to design a Crystal Report (using Crystal Report .NET 2003) and connect Crsytal Report to Oracle 10g Database using Microsoft OLE DB Provider for Oracle. I got this error:
ADO Error Code 0x80004005

So, I think that I should download the latest Microsoft OLE DB Provider for Oracle.
I'm trying to find it in Microsoft page, but I found one which is quite old:

version: 1.0
Date: 31/07/2002

Can somebody help point for me from where to download it?
