Hi Wilfried

Thanks for taking the trouble to respond to my problem. I code compiles without errors in the design environment and runs fine on the old windows 2000 computer. I have even tried compiling the code in windows 2000 and running it on the xp machine but I still get the same errpr message. The COM control just does not recognise that MapPoint 2004 Europe is imstalled on the machine. The copy is a full copy and correctly installed and licensed so I just do not know what to do next. I posted the question in the chnace that someone more experienced than myself had either encounted the problem or knew of it.

Thanks again for your interest
