10 years agoHi,
I used Quartus II 13.0 under Windows 8.1 Pro (x64) and Windows 10 Pro (x64) without any issues. I do not remember if I used for programming USB Blaster or USB Blaster II. If you have not tried it before, try to install the driver manually. To do so select the programming device in either "Devices and Printers" or "Device Manager" -> Properties -> Update Driver -> Manually and select the path to i.e. C:\altera\15.1\quartus\drivers. Now, it should pick up the correct driver. The path depends on where you installed quartus at.
