I'm trying to figure out how to correctly install the WinPcap v4.1.2 on a Windows 7 x64 Ent SP1?! The problem is that I need to silently deploy the WinPcap and it's not possible anymore with the regular installer. So on XP x86 I'm able to copy the correct DLLs to System32 and System32\drivers. That part works great. But on Windows 7 x64 everything installs ok but when I finally launch Wireshark I get an error about not being able to load the DLL wpcap.dll. To make sure I also verify that the npf service is running with "sc query npf" and yes it is. So what am I missing here? Anyone was able to make it work correctly on a 64 bits?

Note: I follow the instructions from http://www.itninja.com/software/cace-technologies/winpcap/4-977.

Thanks in advance for the help!

Weird... I've deployed wireshark to x64 machines, and it seems to work fine...

I think my command line was a /S

Is it all machines or just one?

Sorry but my problem is not with Wireshark. Because Wireshark it's easy with the /S switch. The problem is to deploy silently the WinPcap v4.1.2.
