The capture session could not be initiated on interface '\Device\NPF_{78032B7E-4968-42D3-9F37-287EA86C0AAA}' (failed to set hardware filter to promiscuous mode).

please check sufficient permissions HOW?????? and have the proper interface or pipe specified WHERE?????

Wireshark has gradually become almost unuseable for the casual user. . .usedta just whack capture and get the datastream. BUT I'm aware that the program's utility has increased. God forbid one might have to rtfm. Thanks for the attention. Don

OK, you're using npcap as the capture library, now we need to know what type of interface that is. Can you post the output of

"path\to\tshark.exe -D

replacing "path\to" with the installed location of Wireshark.

finally figured out how to do this. d'oh:

c:\Program Files\Wireshark>tshark.exe -D
1. \Device\NPF_{78032B7E-4968-42D3-9F37-287EA86C0AAA} (Local Area Connection* 10)
2. \Device\NPF_NdisWanIp (NdisWan Adapter)
3. \Device\NPF_NdisWanBh (NdisWan Adapter)
4. \Device\NPF_{68FADA1F-7C7B-46FC-89E6-7CFE16A7E5A4} (Npcap Loopback Adapter)
5. \Device\NPF_NdisWanIpv6 (NdisWan Adapter)
6. \Device\NPF_{1B8B7954-EC44-44C2-908A-04F7FAB9B378} (Local Area Connection)

thanks!
