How do I fix a scenery.cfg error in FSX?

To fix a scenery.cfg error in FSX or FSX: Steam Edition, identify the missing scenery area named in the message, then restore its folder or remove and re-add that Scenery Library entry. Back up the active scenery.cfg first. If its structure is corrupt, rename it so FSX can generate a clean default.

Why does FSX report a scenery.cfg error?

Most scenery.cfg errors after installing an add-on are caused by an incorrect or missing folder path, not a damaged simulator installation. The warning usually identifies an area number and says that its local scenery directory cannot be found.

Typical causes include moving or renaming the add-on, selecting the wrong folder when adding it to the library, disconnecting a drive containing scenery, or allowing an installer to register a directory that does not exist. Clicking OK may let FSX continue, but the warning returns until that entry is repaired or removed.

The folder registered in Scenery Library should normally contain a Scenery subfolder and, when supplied, a Texture subfolder. For example, select Addon Scenery\My Airport, not Addon Scenery\My Airport\Scenery. This worked example of the standard FSX folder-and-library workflow shows the expected arrangement, while these notes on selecting the correct scenery folder level cover a common cause of invalid paths.

How do I repair the broken scenery entry?

1. Record the complete warning. Note every area number and directory shown. Several abandoned add-ons can produce several messages in succession.
2. Check the actual add-on folder. Confirm that it still exists and that Scenery sits directly inside the folder you intended to register. Watch for doubled extraction folders such as My Airport\My Airport\Scenery.
3. Choose the appropriate repair. Restore the folder if it was accidentally moved, reconnect the correct drive if it is external, or remove and re-add the entry when the registered folder level is wrong.
4. Open Scenery Library. After dismissing the warning, use Settings > Scenery Library. Select the affected area and remove it, then use Add Area to register the correct parent folder. If the add-on has been uninstalled, remove the entry without adding it again.
5. Restart FSX. Confirm that the warning has disappeared and that the scenery loads at its intended location.

Never overwrite the simulator's main scenery.cfg with a file included in an old scenery package. Add-ons should be registered through Scenery Library unless their instructions explicitly use a dedicated installer.

Where is scenery.cfg in FSX and FSX: Steam Edition?

The active scenery.cfg is normally under the hidden Windows ProgramData directory, not beside fsx.cfg in your user profile.

Paste %ProgramData%\Microsoft into File Explorer's address bar to reach these folders. If both FSX and FSX-SE directories exist, inspect the entries and modification dates to establish which file your installation is using. Editing the wrong copy is a frequent reason the repair appears not to work.

How can I edit scenery.cfg safely?

Manual editing is useful when the Scenery Library cannot correct the path, but FSX must be closed first because it can overwrite changes when it exits.

1. Make a backup. Copy the active scenery.cfg to a safe location before changing anything.
2. Find the named area. Open the file in a plain-text editor and locate the section matching the warning, such as [Area.123]. Its Title= and Local= lines identify the add-on and registered directory.
3. Correct only the path. A relative value such as Local=Addon Scenery\My Airport is resolved from the FSX installation folder. Scenery elsewhere can use its complete drive path.
4. Preserve the file structure. Do not alter required default areas or casually renumber area and layer values. If the entry needs deleting, removing it through Scenery Library is safer than deleting a section by hand.
5. Save and restart. If Windows refuses to save in ProgramData, edit a copied file and place it back, accepting the required administrator prompt.

What if scenery.cfg itself is corrupt?

Reset the file when it contains malformed sections, duplicate area identifiers, or widespread errors that cannot be traced to one missing add-on.

1. Close FSX completely.
2. Rename the active file from scenery.cfg to scenery.cfg.bak.
3. Launch FSX. A normal installation will generate a fresh default scenery library.
4. Re-add scenery one package at a time. The add-on files remain on disk, but their library registrations and custom priority order must be recreated.

Keep required default scenery areas untouched. When rebuilding the order, place local airports above broad regional scenery where they overlap. Avoid downloading another user's scenery.cfg because its drive letters, installed add-ons and layer structure will not match your system.

Why does the scenery.cfg error keep returning?

A recurring warning means FSX is still reading an invalid path or a different configuration file from the one you edited.

• The package was extracted one folder too deep.
• The scenery folder or its parent was renamed after registration.
• An external drive returned with a different drive letter.
• FSX: Steam Edition is using the FSX-SE configuration while you edited the FSX copy, or vice versa.
• The file is read-only or FSX was running while it was edited.
• An add-on installer restored its old, invalid entry.

Match the exact Local= value in the active file against the real folder on disk. Once those two paths agree—or the obsolete library entry is removed—the scenery.cfg warning should stop.
