Do i need to install WinPcap?

Greetings

Newbie question:

Im new to this BLE and RF world, and i'm trying to read all the info i can before buy the nRF52 DK when it got the IC without all the "erratas" of the preview one (or should i start with the nRF51?, suggestions allowed).

So i install nRF Sniffer and Wireshark, but during the installation of Wireshark it ask me to install WinPCap aswell, did a quick search online and seen it can be used to get into my system, so the question is if i should install it or i can run Wireshark (just for work with nRF Sniffer) propperly without it.
