Can anyone please tell me in specifics how to download aircraft from avsim and have it attached to your aircraft menu on ms2004? I performed download but isnt found in ac library on fs 2004.

HelloI use a program called Addit Pro that will do everything for you. I like mostly because it uninstalls what it installs too. Have a look here www.byteforge.com and you can try it out first. Nothing to lose...........John
