Description

Describe the bug
Hello everyone, I have a problem, I can't use Wireshark, because npcap doesn't install its services :
I have no errors when installing npcap, either through the installer on the site, or through the auto install when I installed wireshark...

To Reproduce
Steps to reproduce the behavior:

  1. When I want to use Wireshark, it informs me that I don't have a capture device, and that I need to start the services with "net start npcap" if Npcap is installed or
    "net start npf".
  2. I get errors when I try to do these commands in a terminal as an administrator.
    And the command "sc query npcap" informs me that there is no service with this name.

Expected behavior
I can't use Wireshark because I can't install the npcap service.

Diagnostic information

  • Windows version from winver : Windows 11 Version 22H2, OS Build 22621.2134)

  • Output of DiagReport
    ➡️I have nothing visible on it when installing npcap / trying to use with wireshark and cmd "net start npcap".

  • Installation logs

  • If installation failed, include SetupApi.dev.log
    ➡️As far as I'm concerned, there are no errors during installation.

  • Any special hardware or software that may be relevant: VPN, firewall, antivirus, virtualization (SR-IOV passthrough, etc).
    ➡️I have a few VPNs installed on my machine (riseupVPN / stormshield SSL VPN Client and Kaspersky VPN). My antivirus : kaspersky (I deactivated it completely during installation, at the same time as Windows Defender.), Virtualization is enabled on my machine, because I'm using VMware Workstation Pro. HyperV is also active.

Thank you in advance for your help !
Kind regards.

Research direction

Review the reported net start npcap, net start npf, and sc query npcap results alongside the linked DiagReport, installation logs, and SetupApi.dev.log guidance. Reproduce the missing-service behavior on Windows 11 with the listed VPN, antivirus, and virtualization context. Done means identifying why the service is not registered and documenting or verifying a resolution.
