NPCAP 0.94 - .CAT file SHA-256 digital signature is bad #406
Description
I originally added this on to the bottom of issue nmap/nmap#875 because I was getting the same "Failed to create the npcap service for Win7, Win8 and Win10" error, but with both 0.93 and 0.94. However as I was writing that, I happened to check the signatures on the NPCAP.CAT file and saw that the SHA-256 signature is bad (see image), so I thought I'd open a new issue.

This is because the
.catfile is not a PE executable, so it cannot have 2 signatures, which is what we are trying to do. We will be changing this in future releases to only have 1 signature (probably the SHA1 signature, since that is most widely supported), but I'm not positive that this will solve the "failed to create service" problem. I'll update this issue when we have a release addressing the 2-signature problem.dmiller-nmap commentedon Oct 2, 2017
Possible temporary workaround here until we can get the next release done: https://github.com/nmap/nmap/issues/875#issuecomment-333598010

Please test Nmap 0.95 and let us know if it solves this problem.

First attempt failed the same as before (failure installing npcap service and hanging at the end). Here's the install log and a DiagReport. Includes trying to install again.
