New CMC firmware updater version 1.11 for Win and Mac

Hi
I have just purchased 3 CMC controllers (CH, QC & AI). I have installed the latest drivers the devices work within cubase but when I try to install the firmware update it’s saying its not recognised. I have tried installing them individually and I am getting the same error message for all 3.
Help please!
OS X 10.9.5 cubase 8 pro 8.010
