Wireshark · Wireshark-users: Re: [Wireshark-users] Question for Wireshark

[Graham Bloice <graham.bloice@xxxxxxxxxxxxx>]

Please do NOT use Wireshark with elevated privileges.  It's totally unnecessary (unless you have unfortunately ticked the npcap option to require admin privs, in which case reinstall npcap and uncheck that box), and more importantly it allows the 2 million + lines of unaudited code in Wireshark full access to your machine, to do as they wish, as directed by any network traffic that may be passing by your NIC.

The original issue may be caused by some sort of failure in the installation of npcap, you can try the standard repair of uninstall npcap, reboot, install the latest npcap version from their website (https://nmap.org/npcap/), or it could be caused by certain anti-virus or VPN products interfering with npcap.

Did you try starting it as administrator?

Hello Wireshark, my name is Stephanie Onyeka, I am a student at Liberty University, and I am currently taking an online course that requires your product to complete assignments. An issue that has happened with both my old and new computer is that although Wireshark will give me a list of interfaces, no packets will load when I click capture. I tried to type tcpdump in the filter box, but it would just come up red. Finding interface details and connecting to my LAN, is what my assignment says to do but I don't see these options in the application. I deleted the old version and downloaded your new version 3.4.4, I'm not sure what to do? What pops up when I start the application is below.
