to VX wings and QX DMX nodes. The new driver has many changes to ensure that this is less

stack in the event of it crashing.
The new driver requires VX wings to be updated to the latest Firmware (v1.15). This update can
be downloaded from

Windows 64 bit Device Driver.
The application that ‘reboots’ the USB stack (described above) requires Administrator privileges
to run. On Windows 64 bit computers this will mean that the “UAC” (User Account Control)

need to manually press [Yes]. Therefore we strongly recommend that you set the UAC to the
“Never Notify” level (as described below) to prevent this dialog from appearing and allow Clarity
to operate seamlessly on your computer.
