Hi, Mark ! I got the 777 Captain Base Package , with no expansions. How do I do to install sp 1.4 ? Do I have to uninstall anything or I just have to run the sp 1.4 exe file?? Thanks

This question has been asked before and was answered by Mark. See Reply#18 (page 2).

"1.4 is a full installer, so backup any 3rd party liveries, then uninstall v1.2/1.3 and then install v1.4 Base Pack (777-200)..."
