OS: Windows 8.1 Professional (64-bit)
WinPython: 3.6.2.0 64-bit QT5
On starting WinPython Control Panel, I get the error dialog:

'This Windows version (6.3.9600) does not support the required Bluetooth API. Consider updating to a more recent Windows (100.10586 or above)'

I assume this is some problem with the underlying Windows/.NET dlls, but can anyone tell me how to fix this error? Winpython Command Line seems to work as normal.
