Here is the hard truth immediately: Oracle 9i (9.0.1, 9.2.0.x) was built primarily for 32-bit architectures. Windows 64-bit existed in beta forms during that era, but the client binaries were strictly 32-bit.
Disclaimer: Oracle 9i was released in 2001 and is now over two decades old. It is classified by Oracle as "Extended Support" expired (typically ended in 2006-2009).
