    Hi reschrei,


    I am glad that the problem is solved on your side. FYI, APU USB Driver is an old driver and won't be compatible with current windows any longer. Only the USB Blaster Driver instead is needed for the latest windows (10 and above).


    Looking forward to hearing your update.


    Regards,

Hi reschrei,


Could you please provide the screenshot of the error message? Also, what is your OS (Windows ver.)?

Affects both my Windows 10 and 11 systems the same (This is from Windows 11 Enterprise 21H2)

If I don't install this driver, Quartus will hang when launching a new empty project with the device selected.

I've attached the DPinst.exe log files. You can see the apu_usb.inf driver fails to install with (0xE000022F). Seems to be an error due to an invalid signature on the driver.
