If you don't have that key, I'm pretty sure you have NOT installed ICOM firmware msis. As those installers are exactly what adds these keys. Without them you will not have this button enabled.

SOLVED:

I had the Firmware installed and it was showing in Add/Remove programs.

I removed the firmware using add/remove programs and rebooted the machine.

Reinstalled using the same MSI as before, and now I have more registry entries and the button appears.

Thanks Node, I can't explain how that happened, but thanks the whole escapade now have a greater understanding of what the MSI does!  Thank you.
