How to determine if platform is win32 or x64 2

[jamsek19]

Hello.
I have specific problem determine on which platform my program is running: win32 or x64.
I tried using GetSystemInfo but its output on x64 platform is wrong - shows that is Intel Win32 platform. Also, I tried with GetNativeSystemInfo but this function just return right value for WinXP or WinVista. On Win 2000 for example, this function is not supported.

Can anyone tell me how to programmticly determine processor platform?

Thanks in advance.

W2000 does not support x64. On this page :

you find a code example dealing with that situation.
