Oracle 11g 64 bit client

I have been working on installing the 64 bit client on a windows 2008 R2 server, to connect to sql. I had the 32 bit client installed not realizing the mismatch. I'm having a hell of a time trying to find the proper download. I searched the forums looking for someone with the same issue I found a post but they had the oracle 10g client but even that find is unavailable on oracle site.

Any help finding the proper install and any guidance would be greatly appreciated thanks.
