See the 'Add or Remove Programs' list of the 'Control Panel' for the installed version. Some annoying bugs are fixed in these versions! If you must use WinPcap, use version 4.1.3. We strongly recommend that you use Npcap. Please use an updated version when possible. Npcap gets regular bug fixes and upgrades on its own release schedule, which means the version bundled with the Wireshark installer may not be the latest. The libpcap file format description can be found at: Development/LibpcapFileFormat Npcap Versions

See CaptureSetup/CapturePrivileges for information about using Npcap and WinPcap with Wireshark. Npcap has a Yes/No comparison chart - Npcap or WinPcap? The Wireshark installer from 3.0 onwards includes Npcap, where versions before included WinPcap.Įven with the older Wireshark versions, Npcap might work better for you, especially if you run Windows 10. WinPcap is for Windows 95 through Windows 8. Npcap supports Windows 7 through Windows 11. 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.
