Infrastructure Navigator licensing asset not showing

I've now deployed twice the vCenter Infrastructure Navigator appliance. I see the Navigator getting registered in the vCenter Web Client, as I have the Navigator Tab and the System Management/Navigator configuration (Enable Discovery & Uninstall).

Yet the Infrastructure Navigator does not register itself in the vCenter Licensing as an asset and so I cannot add the license.

I have to uninstall the Infrastructure Navigator and restart from scratch. Is there a way to force the Infrastructure Navigator to register itself with the vCenter Licensing ?

Thanks,

Erik
