  • Winpcap has been uninstalled totally
  • not check winpcap api-compat mode(Checking doesn't help)
  • OS: win7 64
  • installer: npcap-0.99-r7.exe
  • wireshark version 2.6.4

Tried several times, still can't find Npcap Loopback adapter in wireshark interfaces or ipconfig list

By the way, Basic Filtering Engine (BFE) service is running.

Can you please provide output of DiagReport?

Does running 'C:\Program Files\Npcap\FixInstall.bat` fix the problem?

Unfortunately, running FixInstall.bat didn't help.

Same on win10 1803

Then i use the old version 'npcap-0.80.exe', and everything is back to normal.
