How do I fix Orbx Central’s “library path does not exist” error?

Adam McEnroe
In short

Fix Orbx Central’s “library path does not exist” error, including root-drive rejection, changed drive letters, permissions and broken product links.

Orbx Central’s “library path does not exist” error means its saved library folder is unavailable. Reconnect the drive and restore its former drive letter or volume name; if the location is gone, create a library in an existing subfolder—not a drive root—move or reinstall affected products, then verify them in Central.

This is a general Orbx Central desktop-library issue, not an MSFS-only fault. It can affect content managed for Microsoft Flight Simulator, X-Plane, Prepar3D and FSX.

Why does Orbx Central say the library path does not exist?

Central has a saved path that the operating system no longer presents in the same place. It treats that library location as fixed rather than searching every connected disk for a similarly named folder.

  • An internal or external drive is disconnected, asleep, locked or not mounted.
  • Windows assigned the disk a different drive letter.
  • macOS mounted the disk under a different volume name.
  • The Orbx Library folder was renamed, moved or deleted outside Central.
  • A network share is offline or mapped only for another user account.
  • The library record came from another computer and still contains the old machine’s path.
  • Folder permissions or security controls prevent Central from reading the location.

A changed drive letter is especially common after adding storage or reconnecting several removable disks. If the complete library is still present, restoring its old path is normally safer and faster than creating an empty replacement.

What does “path cannot be root drive or volume” mean?

“Path cannot be root drive or volume” means Central can see the selected disk, but the location is too broad to use as an Orbx Library. Choose or create a folder inside that drive instead.

On Windows, do not select a root such as C:\ or D:\. Use a child folder such as D:\Orbx Library. On macOS, do not select / or the top level of a mounted external volume; use a folder such as /Volumes/FlightSim/Orbx Library.

This is different from “library path does not exist”: the root-drive message means the disk exists but the chosen level is invalid. Creating a dedicated subfolder resolves that specific rejection, provided your account can write to it.

How do I repair the missing Orbx Library path?

Preserve the existing files whenever possible, restore their exact path, and only replace the library record if the original location cannot be recovered.

  1. Close the simulator and pause Central activity. Exit the simulator before changing a library used by it. Let active file operations finish if Central still has access to the location.
  2. Record the exact missing path. Check the full drive letter, volume name and folder names shown by Central. A path that differs by one renamed folder is still a different location.
  3. Test the path outside Central. Open it in File Explorer or Finder. If the drive itself is absent, reconnect, unlock or mount it before editing the library entry.
  4. Restore the former drive letter or volume name. When the files remain intact, give the disk its old Windows drive letter or original macOS volume name. Use the old Windows letter only if another disk is not already using it. Mount network storage before starting Central and under the same user account that runs Central.
  5. Create a valid replacement library if necessary. Open Central’s library management area, commonly found under Settings > Libraries; labels can vary between releases. Select a writable subfolder on available storage, not the disk root, simulator executable or an individual product folder.
  6. Use Central to move an accessible library. If the old location still works but you want a different disk, create the destination library and use Central’s move or migrate control for the products. Dragging the folder in File Explorer or Finder leaves Central’s records pointing at the old path.
  7. Remove a stale entry cautiously. Prefer a relink or move option when one is available. If the old storage is permanently gone, read every removal prompt and distinguish removing Central’s record from deleting product files. Our guide to safely removing Orbx scenery and obsolete library data explains how to avoid deleting a usable installation by mistake.
  8. Verify each affected product. Restart Central, select the installed products and run the available verify or repair command. This checks managed files and can rebuild simulator integration links.

Do not create an empty folder at the old path merely to silence the warning. Central may then find the directory while the product files it expects remain missing, producing failed verification, broken links or downloads stuck in the queue.

Which fix should I choose?

The right action depends on whether the original product files still exist and whether Central can reach them.

SituationBest action
The drive is temporarily disconnectedReconnect it and restore the same drive letter or volume name.
The complete library is visible at a new pathRestore the old path if practical; otherwise let Central move or migrate the products.
Central rejects the root drive or volumeCreate and select a dedicated subfolder on that disk.
The folder exists but cannot be written toCorrect ownership, permissions or security controls before changing the library record.
The disk failed or the product files were deletedCreate a new library and download the missing products again.

Which folder should I use for a new Orbx Library?

Use a dedicated, user-writable folder on storage that will be available whenever Central or the simulator runs. Leave enough free space for installed products, temporary files and future updates.

  • Prefer an internal disk or a permanently connected external disk.
  • Avoid protected operating-system and application folders where a normal user cannot write.
  • Avoid cloud-synchronised locations that may leave files online-only.
  • Use network storage only if it is mounted reliably before Central starts.
  • Select the library folder itself, not one product’s folder.
  • Do not use an MSFS Community folder as a substitute external library unless Central explicitly offers it as the required installation destination.

For Microsoft Flight Simulator, Central may store products in an external library and create links in the simulator’s package location. If MSFS 2020 and MSFS 2024 are both installed, make sure Central is managing the intended simulator rather than manually copying links between their content folders. X-Plane, Prepar3D and FSX use different placement methods, so let Central manage the final integration.

Our Orbx Central installation and library-selection walkthrough explains how the simulator choice, library destination and managed links fit together.

Will fixing the path require another download?

No new download should be required when the complete library still exists and you restore the exact drive letter, volume name and folder path. Run verification afterwards so Central can check the installation and recreate any missing links.

If the storage failed, the folder was deleted or only an empty replacement remains, verification cannot recover absent files. Central must download that product data again. A manual backup can help only if it contains the complete library structure and Central accepts the restored location; do not assume a collection of individual product folders is a valid managed library.

What if the folder exists but Central still reports it missing?

An existing folder can still be inaccessible to the account or process running Central. Confirm access before deleting or recreating the library.

  • Create and delete a small test folder inside the library to confirm read-and-write permission.
  • Run Central under the normal user account that owns the folder. On Windows, an elevated application may not see network drives mapped for a non-elevated account.
  • Check that a shortcut, alias or symbolic link does not point to a missing destination.
  • Confirm the complete path, including volume name and letter casing on case-sensitive storage.
  • Check whether controlled-folder protection, antivirus software or macOS privacy controls are denying storage access.
  • Restart the computer after reconnecting or remapping a disk so Central receives the updated mount information.

If Central cannot save any valid location, does not detect the simulator or fails before you can manage libraries, use our broader Orbx Central fault checks rather than repeatedly deleting library records.

Why is the installation still queued after fixing the path?

A job can remain queued because it was created while its destination was unavailable. Fully exit and reopen Central, confirm the repaired library is selected, then retry or verify the affected product using the controls Central provides.

Do not start several duplicate installation attempts or delete temporary files while Central is processing them. If the queue still does not advance, follow our focused steps for clearing an Orbx installation stuck on queued or installing.
