So installed the programmes and restarted the PC,
Desktop icon opens this: which is also very handy


hooked up to the car and only got a chance to try the INPA as the heavens opened but all, it seems is as it should be. Read errors, activated functions etc no problems. Pulled the seatbelt pretensioner lead off again just so to get the error and re-set it as before no problem.
All told €34 delivered for the software and cable.
