As an admin, you do not have to do any additional setup to get FSACARS working. Simply download FSACARS (http://www.satavirtual.org/fsacars/), and install it (make sure you install the update as well).Then log into your VA, in the pilot center, there is a link to "Download FSACARS Config". It will prompt you to download a file; save the file in your FSACARS directory (typically Program FilesFSACARS). Then open FSACARS, select your VA, and get flyin! The FSACARS config file you downloaded contains all of the necessary information to fly.
