DEP on 64bit executables ?

On a Vista x64 machine when I try and set a DEP exception for a 64bit .EXE I
get the error "You can not set DEP attributes on 64-bit executables"

Does this mean DEP only works for 32bit executable files or that MS thinks
that 64 bit executables will never try to do anything wrong?

Hi Peter,

"System DEP configuration settings apply only for 32-bit applications and
processes when running on 32-bit or 64-bit versions of Windows. On 64-bit
versions of Windows, if hardware-enforced DEP is available it is always
applied to 64-bit processes and kernel memory spaces and there are no system
configuration settings to disable it."

The opposite. It means you can't turn it off for 64-bit processes. MS is
being very strict with all things 64-bit. Requiring DEP, requiring signed
drivers, etc.

Also no timer-stop cracks, no fake bios modding, etc.

Yup. And you know, I think that's all the _right_ thing.
