The WoA Installer does not convert flightplans to FSX format. It only places them in the location to work in FSX.
Alpha India Group does not have an installer. You will have to find and load the aircraft and repaints, then compile the flight plans into traffic files. It sounds like a big job, but even someone as old and befuddled as me can do it - so certainly you can.
Just remember that Flight Sim is a computer program, very literal in what it does. Things have to be in the right place, and have to be done correctly.
