Quartus II Lite edition is not recognizing Cyclone IV EP4CE6 board

Quartus isn't showing any devices in Hardware setup. I know the computer knows it's connected because it shows up in Settings and Device Manager, I've also uninstalled and reinstalled the USB Blaster...

Hi,
thanks for the information. The board uses an external USB Blaster, according to internet offers it comes with a Chinese clone, small black box with light blue stripe and "USB Blaster" printing. Similar devices have been reported not to work with recent (Windows 10) drivers due to non-genuine FTDI chip. They are intentionally blocked by the driver, the adapter is apparently enumerated but not functional. You can review respective discussion here on the forum. Known solutions are using an old (e.g. Windows 7) unsigned driver in Windows 10 test mode.

So, using a Windows 7 driver in Windows 10? That may be a problem since I don't have access to a Windows 10 computer, but if I did, where could I find a Windows 7 driver?
