I don't know how to help you, but I thought I'd share that the AIR Hybrid Synth works on my system.
I'm running Windows 10 x64.
But my version is registered on the laptop itself, not on Ilok.
I DO plan to use Ilok in the future though.
You are using the manual scan right?
One thing to try, transferring the license to the machine to verify if that works without Ilok.
Anything to narrow down the list of what's going wrong.
