[Cannot find pathway with Aircraft]

Hi, I recently bought and installed the Aerosoft CRJ professional into my P3D v5 however I am unable to manually install liveries because I cannot locate my aircraft folder with the aircraft.cfg and other files. I checked my simobjects/airplanes folder and it wasn't there and I also checked my P3D v5 Addons and P3Dv5 files folder and none of these have the folder that I'm looking for. I have a livery that I need to manually install to the CRJ-900 because it doesn't have the liverymanager.txt file in order for me to use the livery manager. How can I find this folder so that I can manually install liveries to the aircraft?
