By default, the Agilent License Service ( flexnet ) is set to "Automatic" start. But it is fragile. A Windows Update reboot will start the service before the network stack is fully online . The service binds to 127.0.0.1 instead of the actual NIC. You download the file again, reinstall, and the problem persists because the installer respects the broken registry key.
