Whois not working

[DeaD_EyE]

Error:
    p = subprocess.Popen(['whois', '.'.join(dl)], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

This module is a wrapper around the unix command whois. On a Windows System the whois command is not installed.
Maybe you can install this in your executable path somewhere: sysinternals-whois

Try this module: https://bitbucket.org/richardpenman/pywhois
If you look on pypi.python.org you'll find many whois packages.
