Windows 10 driver support for USB Blaster ?

In reviewing the drivers download page it appears there are NO drivers for Windows 10 for the USB based Blaster programmer cables. Is this really true ?

2021, this is still the case. Astonishing that they ship drivers that will simply not work for 99% of win10 users

The drivers in Quartus 20.1 are unsigned

I attach screenshot of what my Windows 10 says


Doesn't even complain about hash, just says no.

Had to turn off driver signing enforcement, then worked fine via JTag

Yep that's exactly the message I get.

Specifically how did you disable driver signing?

      Did you try option 1?

      I tried both. The first didn't seem to work though I'll try again. The second bricked my computer. If you have an encrypted drive you need the encryption key to use option 2. IT fixed it but I'm not doing it again.
