Is the Windows system 32 or 64 bit?
What full version is the target Oracle version?

Have you checked your ODBC and OLE drivers againt MS list of currently available drivers?

How To Acquire and Install the Microsoft Oracle ODBC Driver

List of ODBC drivers installed by Access, Office, and MDAC

Installation of the Oracle ODBC and OLE drivers as mentioned by Charles does require a custom install of the client. After running the runtime install just run a custom install and look under the Windows feature.
