    Error when installing driver for serial port PCI in win8.1


    when i try to install a driver for the serial port PCI i get this error message :
    " Windows found a driver for your device but encountered an error while trying to install,
    installation of this device is forbidden by system policy. contact your system administrator . "
    knowing that i am the administrator!!
    how can i solve this error ?
