Record LS-0013, verify the affected product and environment, correct the confirmed prerequisite, and retry once under the same conditions.

Error codes and identifiers
LS-0013

Symptoms

  • The operation fails with LS-0013.
  • The same failure is reproducible in Epic Games Launcher.

Causes and conditions

The official article identifies a product, compatibility, storage, update, network, file, or configuration condition that must be resolved before retrying.

Before you start

  • Exit the game and launcher normally; record the account, title, complete error, and occurrence time.
  • Before changing local saves or settings, find the developer-documented save location and copy it to another folder.

Precautions

  • Launching through a sync warning or conflict can overwrite newer progress with an older save.
  • Do not bulk-delete the game, userdata, or save folders without a backup.

Step-by-step instructions

  1. 01

    Verify game files

    #

    In Epic Library select the game's menu > Manage > Verify and wait for completion; remove mods from the test state.

  2. 02

    Correct privilege mismatch

    #

    If only the game EXE is forced to run as administrator, open Properties > Compatibility and clear that setting so Launcher and game use compatible privilege levels.

  3. 03

    Refresh Launcher webcache

    #

    Fully exit Launcher from the notification area, then remove only Epic's documented webcache folders and restart it. Do not delete saves or installed games.

  4. 04

    Isolate background interference

    #

    Update Windows and close overlays or startup tools one at a time. If only one title fails, inspect its prerequisites and logs.

Check the result

  • LS-0013 no longer appears and the operation completes.
  • The selected version and settings remain after restart.
  • A second test shows no new display, input, save, or synchronization problem.

If the problem continues

  • Restore reversible settings from the notes and escalate without deleting user data.
  • Prefer the PC maker or administrator procedure for OEM drivers and managed networks.
  • Protect account names, tokens, and save contents before sharing logs.

Frequently asked questions

Will running Launcher as administrator always fix LS-0013?

No. Epic specifically calls out privilege mismatch; first review forced administrator settings on the game executable.

Does Verify delete saves?

It normally checks installation files, but review the game's save and mod locations before proceeding.
