Are you installing plain "USB Blaster" or are you installing "USB Blaster II"?  You don't mention what device or board you're using, but you should be installing the USB Blaster II driver.

Both version of USB blaster via the following ways :
1. Go to quartus/drivers folder and click DPInst.exe to update driver. It reports : driver install failed.
2. go to device manager -> altera usb blaster -> update driver -> selected both usb blaster one time and another usb-blaster-ii folder. It reports that most upto date drivers are already installed.

I'm using a Arria 10 device.

USB blaster device :

I even tried to uninstall the driver and plug in the usb blaster device. I was expecting device manager to recognize it as unknown device. From there I install the driver by pointing to the USB blaster ii folder. But device manager doesn't recognize it at all.

      Please ignore my earlier respond as it is for USB BlasterII. I overlooked that you are using USB Blaster. For your issue, could you please follow the steps provided in the link attach below.
