When I enter the command ping 127.0.0.1, in Wireshark there is no result. When I enter 127.255.255.255 the request is visible. DiagReport-20180501-201014.txt When I installed npcap, first there was an error "Failed to create the npf service for win7, win8 and win10". Then I started the installer again and everything was install.

I am having the same issue, but I don't remember that there was an issue during installation. DiagReport-20180612-063421.txt install.log

Loopback capture is only supported by Npcap in native install mode. Wireshark prefers the WinPcap API mode if it is available, which does not support loopback capture. If you install Npcap without the "WinPcap API-compatible mode" box checked, it will work.
