:-( McAfee is running on the machine, but isn't jumping up and down about stuff. Then, as the same user, failed to start it using 'net start npf'. This is all the more vexing, because I have the same version running on my laptop. WinPCap 4.1.2 I even un-installed and re-installed it. To see if the relevant files are present, only to find both of them.
WINPCAP WINDOWS 10 INSTALL
To my surprise, the Wireshark detected Npcap (of appropriate version) and didn't let me install it again.Īnd finally, I checked the: C:\Windows\System32\drivers As a test, I tried to reinstall Wireshark, along with Npcap. So the driver service wasn't running but apparently some vestige of it remained. While installing Npcap, you need to confirm if 'Install Npcap in WinPcap API-compatible Mode' is selected.

The Npcap Packet Driver (NPCAP) service is not started. More help is available by typing NET HELPMSG 3521. The Npcap Packet Driver (NPF) service is not started. Unfortunately, uninstalling Npcap turned out to be harder than I thought, failing and producing following log: With Wireshark still coming up empty, I decided to uninstall npcap also, and start with a clean slate. So apprentlly, the service was present, but couldn't start, because relevant file was missing. The system cannot find the file specified. >sc query npcapīINARY_PATH_NAME : \SystemRoot\system32\DRIVERS\npf.sys
Quick check gave me conflicting information. The situation didn't improve, at which point begun to suspect the driver. Since problems persisted after reboot I decided to reinstall Wireshark with all the same options. Recently, after prompt initiated update, the Wireshark could no longer detect my ethernet interfaces, leaving only USBs on the list.
