With the release of the current ZED-R16 driver release V3.5.5, the soundcard control panel has been renamed and given a new icon.
The V3.5.3 ZEDDICE Control Panel has been changed to the Allen & Heath FireWire Control Panel for V3.5.5

If updating the ZED-R16 driver from V3.5.3 to V3.5.5 you must uninstall the ZEDDICE Control Panel before updating to the new Allen & Heath FireWire Control Panel.

To fully uninstall the ZEDDICE Control Panel you must run the ZEDDICE Uninstaller utility.

Please note that using the Allen & Heath FW  Uninstaller utility that is a part of the latest drivers will not remove the ZEDDICE Control Panel correctly and this can cause a potential driver conflict.

If running a Windows-based PC system the uninstaller utility is located in the
Start Menu > Programs > Allen & Heath LTD >  Uninstall ZEDDICE

If running an Apple Mac OS X based system you will need to download the OS X Legacy drivers from the downloads section on our website, then open the 'dmg' file located in the folder titled ZEDR16Mac_10.5_10.6_Drivers_Firmware_V3.5.3; 
this will open a new window where the ZEDDICE Uninstaller is located.

After successfully uninstalling the ZEDDICE Control Panel reboot the system before installing the current V3.5.5 driver.

If the Allen & Heath FireWire Control Panel is installed whilst the ZEDDICE Control Panel is still present on the system, we recommend uninstalling all instances of the ZEDs drivers from the system and rebooting before reinstalling the current drivers, ensuring to run both the ZEDDICE Uninstaller and the Allen & Heath FW Uninstaller.
