[Winpcap-users] Running 3.1 on 64 bit under 32 bit simulation

WinPcap 3.1 does *not* work on a 64bit version of Windows, even if you try 
to run it under WOW win32 mode. The reason is that on a 64bit machine, the 
user level DLLs can be 32bit (running under WOW), *but* the kernel drivers 
should be 64bit (and WinPcap does use a kernel driver to capture packets).

You need to use WinPcap 4.0alpha1 on a 64bit machine.

Have a nice day
