Re: FW: Advice on npcap uninstall

Ed,

Thanks for this detailed report! We're tracking this issue over at
Github, but I see you've already participated in that thread:
https://github.com/nmap/nmap/issues/906

An initial guess is that the Creators Update to Windows 10 modified
the system so that Npcap doesn't detect itself installed, but sees the
remnants of the install and assumes they belong to WinPcap. I hope to
have a solution to this relatively quickly, but I would encourage you
to update to Npcap 0.92 in the meantime, since it has fixes for a few
other installation-related issues.
