Can't find usb blaster

Hello everybody.

I have a problem with my device. I own a cyclone II.

I use Quartus II 7.2, the thing is that it doesn't recognize my device.

In the programmer, in the hardware setup there is only the option No Hardware.

I need the option usb blaster for it to work.

Windows can't install correctly the drivers and I don't know where to find them or how to install them.

I've read many forums about this but none of them have the solution I'm looking for.

Your help will be appreciated
