Hello Brian,I downloaded the sp1 for default 737 but when trying to install i get an error message saying something like "unable to install , be sure to install main program before installing sp" .Now I'm lost cause the main prog is installed and working ok.Any suggestions?Regards...Marc

Hi Marc,Thanks for bringing that to my attention. I see what happened. Please re-download and re-install the SP1 via the same link.Best,

Hi Brian,Thx for the quick reply.All working fine now.Glad i could be of any help.Regards...Marc
