CMC-PD FW Updater/Catalina 10.15.7

Hi, just moved things over to a new computer and reinstalling items.

I’m taking the time to upgrade the CMC-PD with new firmware.
I cannot run the firmware updater. I get a error message "CMC_FirmwareUpdater.app” needs to be updated.

Can anyone help? Has anyone come across this and what was the solution?
I know is a legacy item.

Thank you
Glenn
