From the main screen, it only shows "Adapter for loopback traffic capture". When I click start capture, it pop ups " The capture session could not be initiated on capture device "\Device\NPF_Loopback" (Error opening adapter: The operation completed successfully. (0)). Please check that you have a proper interface or pipe specific"

Seems like you have an issue with your npcap capture driver. Head over to for more information, the latest driver and see if there's something similar in their issue database.

This sounds like an Npcap issue, so report an issue on the Npcap issue list.

Please give as many details as possible, such as the version of Npcap that was installed and the version of Windows that you are using.
