On Windows, I have used WireShark a lot of times.

Today, I followed the invitation to install 4.0.0, I installed the npcap proposed with the installation. With the new version, I cannot access my Ethernet interface (I tried the Wi-Fi and it worked). I get the message : "The capture session could not be initiated on capture device [...]"

I reinstalled version 3.6.8 leaving the newest npcap and I get the same message.

After that, I uninstalled newest npcap, reinstalled (again) version 3.6.8 but checking the npcap installation.

With this setup, I was able to start the capture on the interface.

I now have a working WireShark but I want to be able to install the newest softwares at some points ! ;-)

Thank you,

Jonathan

Npcap 1.74 and upper doesn't have the problem. Unfortunately, Wireshark 4.0.10 is still proposing to install Npcap 1.71
