Installation
============
The XBirds.exe file can be run from any directory provided the active user has Write permissions on that directory.
From Windows 8 onwards, the Program Files directory has limited permissions, it is therefore recommended that you install the XBirds_exe folder into the folder used for your saved flights within My Documents.

The aixBirds folder must go into your \Simobjects\Animals\ folder, e.g :
C:\Program Files (x86)\Lockheed Martin\Prepar3D v2\Simobjects\Animals
C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Animals
