"This computer has an UEFI BIOS with SecureBoot enabled." message
The Application audio recording method requires Secure Boot to be disabled on Windows 8 or greater systems.
The benefit of the Application recording mode is that each audio source can be isolated, providing a clean recording.
You can still recording in Stereo Mix capture mode without disabling Secure Boot, but then the recordings might overlap with other audio playing on your computer, such as system sounds. You will need to be careful to turn off system sounds and not have any other audio play during a recording.
