i have managed to bypass the licence on the older software so all i need is the install for the latest software and i might be able to get there.Not sure I understand why you have made the above comment. As you know that mine is a licenced version .
My SEVCON DVT is now a fully licenced version and unless you pay for a licence, it cant be loaded. Each install needs a separate licence. So both mine have a separate install script supplied as part of my licence payment. This has to be renewed annually, and a new code used on each install. I have explained this previously.
