Wireshark Does Not Recognize Adapter

I am attempting to capture data using Wireshark and am getting this error message:

"The capture session could not be initiated on interface '\Device\NPF_Loopback' (Error opening adapter: A device which does not exist was specified. (433))."

So I went into Wireshark Options and am attempting to add an Input Capture Interface. How do I do that?

I had the same problem and couldn't fix it at all until today.

What I did was install an older stable version of Wireshark (v2.6.11 it is) and it works now.

So try this out and I hope it'll work for you as well.
