Installing in this suggested order worked for me after trying many other things. Of note, when I installed npcap I unchecked compatibility mode.
The procedure noted by schester worked for me too. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
The ncpap binaries are signed by the nmap signing certificate Insecure. Wireshark bundles a locally cached copy of the ncap installer into its installer and doesn't modify it in any way. You should consider reporting your issue especially the signature failure to the npcap folks who are in a position to investigate. I don't know how this has come about, but you can try starting the service from an elevated cmd prompt with net start npcap. You might also need to start the Base Filtering engine bfe with net start bfe.
The npcap installation directory also provides a helper batch file FixInstall. This should also be run from an elevated cmd prompt.

Unable to capture packets on Surface Mobile Broadband adaptor. At what stage does Wireshark check which capture library npf is installed? Is Wireshark v2. The error message appears in the area of the application window where you would expect to see a list of available networks. To capture network traffic packets, you first need to select one of these networks.
There are many possible reasons for this problem. Surprisingly, in Windows, you do not need to run Wireshark with administrator network privileges to give the program access to network functions. One element of the Wireshark suite of programs does need administrator network privileges. This is WinPcap , which is the underlying service that assists in capturing packets.
The setup process of Wireshark will install WinPcap for you. The installation process sets WinPcap to run on system startup and also writes it to the register so that it can run with admin rights level. It is this installation phase that requires you to restart your computer. Linux users report a different situation when running Wireshark. It seems that it needs to be run with the sudo command.
This action runs the normal program with superuser network privileges. This is dumpcap ; you need to run the following command to get this module set up properly. It may be that the Wireshark code is held in the bin directory instead of sbin. If the above command returns an error, try:.
Close down Wireshark and turn off your firewall. Open Wireshark again to get it to look for networks. If it now manages to find the network, the problem lies with your firewall. Set Wireshark as an exception in your firewall rules and turn the firewall back on again. If none of the above tests on the software running on your computer solve the problem, you will need to test your network card.
It has done this time s. The following corrective action will be taken in milliseconds: Restart the service. I can't seem to find anything regarding this or if I am missing something. The prereq doesn't seem to show anything special missing so i am stumped. Any help is welcome. Tony escamilla , Also, can you make sure the Pla service is running correctly on the machine?
I have had this issue pop up recently. Server R2. The Open Procedure for service ". PcapException: No interfaces found! Instantiate at void Microsoft. AddModules Type[] moduleTypes at new Microsoft. CreateModuleManager at async Task Microsoft. OnStartAsync at void Microsoft. Await Task task at void Microsoft. OnStart string[] args. As to why winpcap did not work for your case, it's hard to tell, usually it means there is another product installed that is also using winpcap but with a configuration we do not support.
If you would like to research it a support call might be in order, but if npcap just work for you, I guess that would be a waste of your time Eli Ofek Wireshark was also installed on the machines, I figured that was where the issue may have come from. All is well now. I actually get the same errors as jomalin but with one exception on these servers and it is mixture as some are R2 and others are I also never have installed WinPcap.
I wasn't planning on installing npcap either as it doesn't look like it requires it unless i have a physical server and require NIC teaming. In my case all the servers 4 are running on VMware so the only requirement is the change on the NIC adapter being used. As for npcap it seems that my installs work fine until the update process goes out and looks for updates and that is where all hell breaks loose.
NpCap then gets installed which it seems is coming from the sensor but I have not been able to trace where that install is coming from. What makes it even more weird is that it is only affecting 4 out of the more than 10 DCs we have in our environment.
Should I install Winncap to see if all works fine then. I do have a support ticket opened with support but we are just stumped as to why npcap is just being installed on these and not the rest.
Tony escamilla I am not aware of any code in the product that is installing npcap automatically. If you have a support ticket open already then they should be able to tell why the failure is happening. One thing to note so i did a complete new install of the sensor. There was no Npcap or winpcap or wireshark installed on the system.
