fixed problem with pywintypes.com_error

[FelixEL]

Important fix to gui_tool not beeing able to detect PCAN (and other interfaces) on windows:
pywintypes.com_error: (-2147221020, 'Nieprawidłowa składnia.', None, None)

Error happens when method detect_available_configs() is executed. It happens when periodic scan of interfaces takes place.

Fix for common error in windows:

thanks for reporting this!

I think this either needs a check for windows, or at least a try/except wrapper
