Hello;Since this is my first visit here, hello all!I like the look of your site.I read somewhere but cannot trace the source that one has to have the MSFS2002 program installed, to be able to directly transferany 2002 addons you might have and want to run in the 2004 version.If not, the article noted you cannot install any previous, i.e. 2002 addons,by direct installation from off the WinXP C: drive.Would you please confirm this so to help me decide the best route.Thank you,CWA....
