I got a DELL 64-bit server that I am configuring with W2K8 Standard 64-bit.
I've got plenty of disk space and made my C: partition 60GB. I noticed by
default W2K8 created a C:|Program Files and a C:\Program Files (x86)
directories. Pretty much self explainatory. When I load 64-bit apps by
default the install directory points to C:\Program Files I assume because it
recognizes the application as being a 64-bit app. On the other hand when I
load a 32-bit application be default the install directory points to
C:\Program Files (x86).
So my question is are 64-bit applications required to be installed in the
C:\Program Files directory in order for it to be recognmized and run as a
64-bit app or can I create and install all my 64-bit and 32-bit applications
on a different partiton such as D:\Program Files for 64-bit apps and
D:\Program Files (x86) for 32-bit apps?

It was always and still is possible to install apps in a folder of your
choice, even on another volume.
Program Files and Program Files (x86) is just a matter of Microsoft's
default setting and recommendation.

BTW, on 64-bit OS, 32-bit apps work in a WOW64 subsystem. Architecture of
the app is not recognized by it's placement, but by it's internal structure
(headers, libraries it uses etc).

Summary,
Unless you have a good reason to place an app in a different place, leave
the default placement.

Dusko thanks for your input. I kind of knew the reasoning for the 2 default
Program Files and Program Files (x86) directories was to seperate 64-bit and
32-bit apps. My main concern was whether or not the program files folders
had to be used on the OS (C:) volume only and if not then I could create the
2 folders on a different partition such as the D: drive.

Yes, you can create folders on a different drive (for example D:). You can
even name them the same (Program Files and Program Files (x86)), although I
would choose a different name. I'd choose a different name if I'd like to
install another OS in the second volume (Win2008R2 or Win7). In that case,
my new OS would have a slight problem because default names already exist.
I'd just create one folder named 'Programs' on D: and when installing new
software, I'd point the installer to that location.
