Hello, 

I face the same error.

I have tried to run the latest Windump (3.8 alpha) with rpcap also. (For
sure I have run the rpcapd with -n flag). But still failed to find the
adapter.

I have tried both syntax:
Windump -i rpcap://127.0.0.1/\"adaptername"  and 
Windump -i rpcap://"IPaddress"/\"adaptername"

And the error is:
windump: Error opening adapter: The system cannot find the path specified.

I wonder what is the correct syntax for using it with rpacap? 

Thanks in advance.

This is my last try.
Do you launch the rpcapd daemon with the "-n" switch? WinDump does not
manages password, so you have to launch the daemon in such a way that
supports NULL authentication (that means "everyone can capture traffic on
your machine... so please be careful).
I cross my fingers...
