Oracle 64 bit version

I need to download Oracle 11G for Windows 2008 server (this OS is 64 bit). If I go to the site, I see two options

Download Microsoft Windows Server 2008 (32-bit)
Download Microsoft Windows Server 2008 x64

The first one I understand is the 32 bit version. Is the second one 64 bit version. I am confused as it does not say 64 bit but instead says x64.
Secondly, can the 32 bit version Oracle work in 64 bit OS.

thank you

x64 is the same as 64bit.

I've never tried but I believe Oracle 32Bit will run under Windows 64Bit but why would you want to?

x64 is Intel 64 bit (as opposed to Itanium 64 bit), so that is the right one to download.
Yes, you can use Oracle 32bit on a 64bit system.

Not an answer to the OP, but you might have third-party apps that are not certified against Oracle 64bit.

Good point.  I would hope I could install the 32Bit client and still run my DB 64Bit.

'Hope' being the important word.  :)

I see no reason why using a 32bit client and 64bit server on the same machine should not work. And I would prefer that, too, no matter if I intend to exhaust the memory limits imposed by 32bit.
