It has been reported as not working by several other posters, but I can report that it has always worked for me on both Vista and Win7. What are the Network Sniffing Options set to? I have WinPcap v18.104.22.1682, Snooper v2.20.01, using Microsoft network adaptor.
I can not even get the program to start. What you mean program sniffing options set to??? I guess maybe I am doing something wrong. Did you install both programs seperate or in the pack off of the Roku website? Help me a little bit more here and maybe I can get it to work.
I may have upgraded WinPcap by another application but that is not relevant, since Snooper has always worked. Install again but do it as administrator (right click installer and select Run as administrator option). Also run it as administrator.
Sniffing options can be found on the General Options tab if you get it running.
