Just to shed a bit of light on this issue (or maybe not). The error is
caused by the fact that the wrong version of packet.dll is installed. In
practice on some Vista systems the XP version of packet.dll is installed,
and that version does not work on Vista.
We have had similar reports with the standard WinPcap installation, and so
far I haven't been able to track down why that happens. The only reason that
I found so far is that the installer on Vista was run in "windows XP
compatibility mode", causing the wrong files to be installed. But this is
just an idea.
Have a nice day
