Error when you install a third-party Bluetooth driver in Windows 8


When you try to install or reinstall a third-party Bluetooth driver on a computer that is running Windows 8, the installation fails. Additionally, you receive an error message that resembles the following:
Could not open Key:
HKEY_LOCAL_MACHINE32\SYSTEM\CurrentControlSet\services\BTHPORT\Parameters\Radio Support
Verify that you have sufficient access to that key, or contact your support personnel.


This issue occurs because Windows does not provide the BTHPORT subkey with sufficient permissions to open the registry subkey.
