Fix “A driver cannot load on this device” for Winlo64.sys on OPS x12UW in i3TOUCH Ultra

If you see the “A driver cannot load on this device” message for Winlo64.sys on your OPS x12UW (ultrawide) PC in an i3TOUCH Ultra display, it’s because Microsoft has flagged the DssAudioService audio driver as vulnerable and blocked it in recent Windows 11 updates. This article guides you through replacing the blocked driver so your audio works smoothly again.

This article is for IT admins or users managing i3COMPUTER 512UW or 712UW OPS modules in i3TOUCH Ultra displays. If you’re using a different OPS or display, these steps won’t apply.

By the end, your OPS x12UW should have working audio with the updated driver. If the new driver fails to install or the error persists, contact i3CONNECT support.

Before you start

• Make sure you’re using an OPS x12UW (512UW or 712UW) in an i3TOUCH Ultra.

• You’ll need admin rights on the OPS PC.

• Download the updated driver before uninstalling the old one.
