Yes, now sorted thanks Joop, but I have installed 4.01 libraries which I can see in the installed packages but I cannot tick the box to show that it is working ???

Hi
I am running windows 7 and am trying to install NL 2000 v 4.01 EHD. I have installed the NL2000 v 4 library file but I am getting an error message saying I have to pre-install NL2000 v 4.0 library or higher ??? I managed to install Fotoscenery Zuid-Holland earlier. Any advice please ??
