Installation
Installation is really simple. You only have to download the "A32NX" folder.
For the Microsoft Store edition AND/OR Gamepass edition:
Copy the "A32NX" folder into your community package folder. It is located in: C:\Users\[YOUR USERNAME]\AppData\Local\Packages\Microsoft.FlightSimulator_<RANDOMLETTERS>\LocalCache\Packages\Community.
For the Steam edition:
Copy the "A32NX" folder into your community package folder. It is located in: C:\Users\[YOUR USERNAME]\AppData\Roaming\Microsoft Flight Simulator\Packages\Community.
For the Boxed edition:
Copy the "A32NX" folder into your community package folder. It is located in: C:\Users\[YOUR USERNAME]\AppData\Local\MSFSPackages\Community.
If the aforementioned methods do not work:
You can find your community folder by going into FS2020 general options and enabling developer mode. You will see a menu appear on top. Go to tools and virtual file system. Click on watch bases and your community folder will be listed in one of the folders.
Please make sure you're copying the "A32NX" folder into your community package folder, NOT the "msfs-a320neo-master" folder.
