After installation there is no network interfaces finded. Only the loopback interface is present. Is it possible to find interfaces manually ?

Thanks

Presumably this is on Windows, so is likely to be an npcap issue (if using the current version of Wireshark).

Can you copy (highlight the text with the mouse) and then paste the contents of the Help -> About Wireshark dialog into a comment here?

You're running the latest stable version of Wireshark and the latest version of npcap so that's good.

Can you run the following command in an elevated command prompt and post the results back here:

'C:\Program Files\Npcap\DiagReport.bat'

Note that the contents of the report might be too big to post as a comment, so you'll have to upload it to a public file share, e.g. Google Drive, DropBox etc. and then post a link to the file back here.

That seems to be the contents of the batch file, not the diagnostic report it produces. You have to run the batch file from an elevated prompt, it will produce a report (opened in notepad for your convenience), and that report is what I'd like to see.
