[Winpcap-users] Problem on Vista x64

I think I know the source of the problem. Have you started the command prompt (where you run nmap) with elevated privileges, i.e. right-clicking on the link and choosing "run as administrator"?

I think you are hitting UAC: even you are an administrator, you are running in a restricted security context that doesn't allow you to start the winpcap driver.

Have a nice day

  I tried to install the latest winpcap (4.0) on 64bit machine (2K3 and Vista), tested with Nmap and it works nice on 2K3 but got error message on Vista, which is:
    dnet: failed to open device eth4

  Any clue that might help ? 

  FYI, I used the latest installer downloaded directly from winpcap site, and not the one from Nmap.
