1. Uninstall all Integrated Webcam devices (there were two in my device manager for some reason), all Tobii software 2. Delete all Tobii registries then remove any facial setup recognition in Windows Hello 3. Reboot and install latest Tobii Aware 4. Turn off the switch in the Tobii tray menu (important i think) 5. Check device manager again and uninstall any Integrated Webcam devices that resurfaced. 6. Download Realtek IR driver from Dell and install 7. Reboot when prompted and setup Windows Hello 8. Then turn on the switch in Tobii tray menu! Everything worked again afterwards :)
