The win7 device manager detects nothing when JTag is connected to laptop

I tried to use the JTag cable by connecting it to the USB port of my laptop. By following the instruction of driver installation: https://www.altera.com/support/support-resources/download/driver...

Dear Alex,

Thanks for your response.

Yes, Quartus is installed.

There should be a unknown device when the JTag cable is connected to the USB port.

However, there is actually no unknown device found in the Device Manager. That's the problem. (Neither the USB Blaster nor an unknown device shows up.)

Therefore, I can do nothing to deal with the driver.
