• I'm in the same situation, also lost my internal Bluetooth port after using Zadig and not been able to restore it. Bought an external BT dongle, but pairing is not working on my Win 8.1, on Win 10 pairing is successful, but as that's a 32-bit system I'm out of luck there as well...
    Waiting for @Gordon to return from his well deserved break to hopefully be able to help
