How are you installing the driver?
The log indicates you are doing a "force" install and you are pointing it to the Arduino USBSerial.inf file.
First, you should not need to do a force install.
Second, you are forcing it to use the wrong file.
The following procedure will help you install the drivers for your Arduino board on Windows:
Go to Device Manager
Right click the Arduino device in Device Manager
Select Update Driver Software
Select Browse my computer for software
Click Browse button
Select the Drivers folder under the location of your Arduino software installation. (Do not select the FTDI folder inside the Drivers folder)
Click OK
Click Next
