Is there a way I can find what CPU family my application is running on?
I am trying to find if the processor is a 64bit or 32bit.
Is there an API exposed in the framework?
Any help will be helpful.

thank you,

There's nothing out of the box, but Mentalis has a nice wrapper around the
Win32 interfaces.

Do you want your app or the processor? Could be different. You can use
Marshal.Sizeof(IntPtr) to fnd out if your app is 32 bit or 64-bit. I thought
they were adding a NET class property someplace in 2.0 but I can't find it.
You can see if the processor is 32-bit or 64-bit by using the
ManagementObject and related classes to get to the WMI Win32_Processor
class, where the AddressWidth property is either 32 or 64.

thanks Phil
System.Management solved my problem crudely.

Apprently I could not use Address width for my problem as I cannot
completely reply on Address Width
my guess is because as WOW processes are created on x64 machines if the OS
installed on a x64 machine is 32 bit.... the address width will be 32 and
not 64.(correct me if I am wrong)
So I had to go with the Name and find the value 64 within the name of the
processor.
If there is a better way please do let me know.

here is a WMI VBscript I found on the net
