    Looks like your previous installation of lns didnt completely remove itself.

    Uninstall Look 'n' Stop firewall - reboot.

    Delete folder Soft4Ever
    Located in C:\ProgramFiles\Soft4Ever

    Open regedit.exe - Delete lnsfw1 regestry key located in -

    Start menu - R Click My Computer, select Manage, select Device Manager, select View and select Show Hidden devices.

    In the middle window click the Non-Plug and Play drivers triangle, R-Click lnsfw1 and uninstall it.


    Download a fresh copy from

    Disable antivirus, hips, etc. Some security software will stop lns driver installation.

    Re-install Look 'n' Stop.

    The Windows registry PNP_TDI list was corrupted and preventing Look 'n' Stop product from installing, hence the error message. The Windows PNP_TDI has been rectified, which lead to a successful install of Look 'n' Stop on this user PC. :)
