gns3 error --- cannot start console applications
cannot start console applications: [WinError 2] The system cannot find the file specified.
I got this error, upon checking I found that I had not installed wireshark during installing gns3. Installed wireshark separately and the error is gone. I did no configuration except installing wireshark.
I can see and capture traffic on gns3 device's interfaces by just right clicking any interface and then clicking "start wireshark".
