Urs,
I think I have found the problem. The laptop is also setup for another network when I don't use it for EFB and the "My documents" folder is somehow placed on a network drive on that network. So when I am not on that network it doesn't find the "My documents" folder and just dumps the Aivlasoft folder on the desktop.
I am going to install it on another laptop and then I think everything will work.
Thanks for the help and blue sky.
Regards
Oyvind
