I have redownloaded wireshark multiple times and I keep getting a message that says "no interfaces found" right below where it says "Capture a filter". I'm wondering how I can fix this issue since I am unable to do the labs in my class since I can't select an interface to use.

We cannot answer this question since you say nothing about the system to install on.

Can you post the contents of the menu Help -> About Wireshark dialog? You can highlight the text and Ctrl + C it to the clipboard and then edit your question to add it to the bottom.

Graham, I just edit it and posted the contents. Hopefully that was what you were looking for, thank you.

The key bit of that info is from the "running" part:

with Npcap version 0.995

This shows that you do have a capture library installed which should be giving you your interfaces.

It's likely that npcap was installed along with Wireshark, if so did you modify any of the npcap options?

You should also consider uninstalling that version (from the Settings -> Apps thingy) and installing the latest version from the npcap website (currently 0.9983).
