How do I install the Fenix A321 in MSFS 2020?

To install the Fenix A321 in MSFS 2020, own and install the Fenix A320 base package first, then use the latest official Fenix Installer while the simulator is closed. Sign in, select MSFS 2020 and the correct Packages location, install the A319/A321 expansion, and launch the Fenix desktop app before loading the aircraft.

What do you need before installing the Fenix A321?

The Fenix A321 is an expansion for the Fenix A320 and runs only on the Windows PC version of Microsoft Flight Simulator 2020. It cannot be installed on Xbox because it depends on external desktop software.

• The Fenix A320 base product must be owned and installed.
• The A319/A321 expansion must be registered to the same Fenix account.
• MSFS 2020 and the Fenix desktop app should be closed during installation.
• You need the Packages location actually used by MSFS, especially if you moved it to another drive.

If the base aircraft is not working yet, complete our Fenix A320 setup and installer procedure before adding the expansion.

How to install the Fenix A321 in MSFS 2020

Install the aircraft through the Fenix Installer rather than extracting files manually into the Community folder.

1. Confirm your account: Sign in to the Fenix account that owns both the A320 and the A319/A321 expansion.
2. Close the software: Exit MSFS 2020 and the Fenix desktop app so that package files are not locked.
3. Obtain the latest installer: Download the current official Fenix Installer from your account rather than reusing an old saved installer.
4. Select MSFS 2020: Run the installer, sign in and choose the MSFS 2020 installation if it offers more than one simulator.
5. Check the Packages location: Select the folder used by MSFS for its packages. This is normally the parent folder containing Community and Official, not the simulator executable directory. For a custom installation, it should agree with InstalledPackagesPath in the simulator's UserCfg.opt file.
6. Install the expansion: Choose the A319/A321 expansion, or the equivalent family component displayed for your account, and let the installer finish all required downloads and updates.
7. Start the supporting app: Open the Fenix desktop app and confirm that it is signed in, then launch MSFS 2020 and find the Fenix A321 in the aircraft selector.

The core aircraft should not be dragged into Community or installed under Official. Our guide to dedicated aircraft installers and Community packages explains the difference for other MSFS add-ons.

Why is the Fenix A321 not showing in MSFS?

An absent Fenix A321 usually means the installer targeted the wrong Packages folder, the expansion entitlement was not detected, or the base A320 family installation needs updating.

• Wrong Packages folder: Rerun the installer and compare its path with InstalledPackagesPath. Multiple unused Community folders are common after moving MSFS to another drive.
• Wrong account: Make sure the installer is signed into the account used to purchase the expansion.
• Incomplete family update: Use the installer's update or repair option for both the base A320 and the expansion. Mixing an updated expansion with outdated shared components can stop the aircraft loading correctly.
• Fenix app not running: Start the desktop app, sign in and leave it running while using the aircraft.
• Aircraft selector filters: Clear filters and search for A321 or Fenix rather than relying on the last manufacturer or aircraft-type filter.
• Security software interference: Check whether Windows security software quarantined a Fenix component. Restore only a verified official file, then run the installer repair rather than disabling protection entirely.
• Conflicting additions: Temporarily remove third-party Fenix modifications and old A321 liveries, but retain the official aircraft package, then test again.

How do you update or reinstall the Fenix A321?

Use the same Fenix Installer to update, repair or reinstall the A321 expansion. Close MSFS first, verify that the installer still points to the active MSFS 2020 Packages location, and update the shared A320 family components together rather than deleting individual files by hand.

Can you add liveries after installing the A321?

Install additional liveries only after the unmodified aircraft loads successfully. A repaint must be made specifically for the Fenix A321; an iniBuilds A321 or generic Airbus livery is not interchangeable. Follow our instructions for compatible Fenix A321 liveries to avoid nested folders and mismatched variants.
