The current and last WinPcap release version is 4.1.3. Some annoying bugs are fixed in these versions! We strongly recommend that you use version 4.1.3 or 3.1. See the "Add or Remove Programs" list of the "Control Panel" for the installed version. Please use an updated version when possible. Since Npcap is just getting its first widespread exposure to the world unexpected issues may arise. The libpcap/WinPcap file format description can be found at: Development/LibpcapFileFormat See CaptureSetup/CapturePrivileges for information about using Npcap and WinPcap with Wireshark. Even with the older Wireshark versions Npcap might work better for you, especially if you run Windows 10. The Wireshark installer from 3.0 onwards includes Npcap, where versions before include WinPcap. One of them must be installed in order to capture live network traffic on Windows.

Npcap and WinPcap are Windows versions of the libpcap library.
