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
