Thanks Cameron, I was working on your last repsonse, dated 3rd April where you indicated that you were "still investigating". I thought we were corresponding via email on this and I haven't received anything from you since the above. I have just been over to x-aviation and can't find any reference to this ticket and suggestion? Can you please clarify where to look or just email it me? I am just as dumbfounded as you as to why this installer does not work, I apologise if you misread my requests for help as something else, I have been working with computers since the mid 80's so feel I have half an idea about them, I just hadn't heard anything since the 3rd April and am not familiar with this x-aviation 'ticket' thing. Thanks for your time.
