I installed wireshark 32bit version on a machine and whenever i run it(as administrator) and try to click on the only connection listed i get the following error:

The capture session could not be initiated on interface '\Some\Path' (Error opening adapter: The system cannot find the path specified. (3)).

Please check to make sure you have suficient permissions, and that you have the proper interface or pipe specified

I've tried uninstalling and reinstalling and the same issue occurs. What should I do? Note that '\Some\Path' is not the real path

It helps if you include the information from "Help->About Wireshark" or "wireshark -v".

What is the connection listed?

What is the path that appears in the error message? (Not an example, the actual path.)

What is - as bubbasnmp says - the version information for Wireshark? This is an error from WinPcap/Npcap, so we need to know what version of WinPcap or Npcap is being used.

The connection listed on the "home" screen is: Adapter for loopback traffc capture

As for the path: 'Device\NPF_Loopback'

And at last, the version of WinPcap/NPcap is Npcap version 0.9983, WinPcap SDK (WpdPack) 4.1.2

npcap has info here on running a diagnostic report to check the interfaces:

"Npcap has provided a diagnostic utility called DiagReport"
