In order to get the POSKY 777 VC to work in FSX you need several things:1. POSKY FSX model & interior model2. FS9 Boeing 777 gauges3. msvcr70.dllYou can do the merge yourself following any of the many good tutorials that are available online.Another option is to download a complete aircraft/vc merge that some nice person has already taken the time to do and upload. For example, you could use one of these: http://simviation.com/1/search?submit=1&keywords=fsx+posky+777+united&x=0&y=0 to get started, then just add textures for any additional aircraft that you would like.Hope that helps.
