Carnivore library for Windows

Hi everyone,
I wanted to know if some of you had already tried to play with the Carnivore library ; wich require WinPCap to be used on Windows. Do I have to do something with it ;or just launch it and the sniffing will be set automaticaly ?

For the moment, it doesn’t detect my network, so I can’t run the sketch. Carnivore isn’t breaked : I use it on MacOS.
If you have any advices or if you know how to set it on W, I would be glad to hear it !
