DDJ 1000 Screen not working. Shows NO AUDIO DRIVER

Did you actually install the audio driver?

I've had this controller since Feb and everything was working fine until today.

I've reinstalled the driver again and it managed to get it going.

The question is Why did it do that? I haven't moved or deleted the driver or anything

Was there a system update? Which OS are you using?

I have Windows 7 x64, it can't install Audio driver because it's not signed. Where can I find signed driver?

Try a Security Update for x64 bit based Windows Systems

@Kirill > You don't have all of your system updates installed. Please ensure that your Windows 7 has all service packs and all of the available updates installed first.

Ahaha, you forget to mention "turn off your antivirus and clean your system with special programs CCleaner and etc". You don't understand, that problem not with my Windows. Your driver doesn't meet security criteria to run on Windows. Every driver must be signed because without digital signature malware or virus can install system driver and become invisible to system. x86 systems allows to install unsigned drivers, Windows 7 x64 - don't allow. So, update your drivers with digital signature (ask technical department or what do you do in that cases).

Here's the problem...

A couple of years back, Pioneer DJ was part of Pioneer Electronics Inc., which was how the drivers and software were also signed. You're likely using a version of Windows 7 which had the driver signature registry from that time. After the switch, all of our drivers and software were signed as Pioneer DJ, but as our driver files don't match your registry - no installation.

You CAN install unsigned drivers or those that don't match, you simply disable the driver signing first, but I'd recommend updating to an operating system for which Microsoft didn't end support back in 2015.
