    "There was an error while opening Windows Firewall." on Windows 7 System.

    Whenever I attempt to open the Firewall on my machine, am getting a square window with the message "There was an error while opening Windows Firewall." I just double clicked on the Windows Firewall in Control Panel and got a window with this message. What can be done now and why it is blocked to open?
