[Winpcap-users] Npcap 0.04, based on original WinPcap 4.1.3, call for test

[食肉大灰兔V5]

Hi, Petr and Guy,

First thanks for test. In fact Npcap only adds its program folder to
system's "PATH" only when Npcap is installed NOT in "WinPcap Compatible
Mode". The None-"WinPcap Compatible Mode" is only for future version's
Nmap. So you should *ALWAYS* has *"Install Npcap in WinPcap API-compatible
Mode"* option checked when installing Npcap (which is the default option).

For None-"WinPcap Compatible Mode", Npcap's NSIS installer uses
*${EnvVarUpdate}
$0 "PATH" "A" "HKLM" "$SYSDIR\Npcap"* to add a path and *${un.EnvVarUpdate}
$0 "PATH" "R" "HKLM" "$SYSDIR\Npcap"* to delete the path (see:
https://github.com/nmap/npcap/blob/master/installer/NPcap-for-nmap.nsi, Line
698 and Line 785). I hope I am using it right, if I am wrong, please
correct me:)

Cheers,
Yang
