Error from installing npcap: 0x80070005

[HuyTyskland]

Hello everyone,

I am trying to install the npcap for Wireshark and I met this problem:

I tried to install the latest version many times but nothing worked.
So how can I fix this error?

Thank you, Huy Nguyen.

+1 Same issue here. I shouldn't have uninstalled the previous version of Wireshark. I tried installing the new one with the updated npcap and now I'm stuck.

I have the same problem. Try running the same version of Npcap on a windows virtual machine. I did and it works fine. Therefore, I know the problem is coming from my PC and not Npcap . I think the problem comes from windows version or something is blocking the NDIS filter drivers from installing.

Therefore, you know that the problem does not occur on all installations of Windows on all machines.

That does not imply that the problem is with the installation of Windows on your machine; it could be that there's something broken about the installation of Windows on your machine, but it could also be that there's something unusual, but completely valid, about the Windows installation on the machine that's having the problem and that Npcap needs to be modified to deal with that.

If it's the formatter, and Npcap can't work around it, it might be nice if it could detect it and report it, to indicate that something needs to be fixed.

If it's the latter, Npcap needs to be changed to handle whatever the issue is.

0x80070005 appears, from some Web searches, to ba an ACCESS_DENIED error of some sort. According to Microsoft's description of the format of NT status values, it's STATUS_SEVERITY_WARNING (0x8......., not 0xC.......), and the facility code is 7. According to this Microsoft page, facility 7 is FACILITY_NTWIN32. If that means "the code part of this is a Win32 error code", then, according to Microsoft's list of Windows error codes, is ERROR_ACCESS_DENIED, the error message for which helpfully explains that pitmans that "Access is denied".

Understood, thank you. I ran multiple versions of Npcap including the latest just to see what would happen and all failed to install on Windows 10 OS build 19044.1826 physical machine.

Npcap-0.9991: LWF driver has failed to be installed.
Npcap-1.60: Unknown error! 8007007e when installing NDIS filter driver and also LWF driver has failed to be installed.
Npcap-1.70: Packet Driver (NPCAP) has failed to be installed.

Hello guys,
if anyone still has this issue the problem for me was caused by an NDIS driver on the network driver. For me, this driver came with VirtualBox. You can uninstall this driver by going to the network connection properties window and then in the networking from the wifi/ethernet properties there will be one driver called something with NDIS in the name, uninstall this by clicking the driver and then clicking uninstall the error should now be fixed and you will be able to install NPCAP.

I do have this installed, but unfortunately I get the same 8007007e error when trying to uninstall or disable it...
