Tools You'll Need

How to Fix Error Code 1007

  1. Restart Steam Completely

    Make sure Steam has fully finished any active downloads or updates before force-closing it, or you may corrupt a partially downloaded file.

  2. Wait for Active Downloads or Updates to Finish

  3. Clear the Steam Download Cache

  4. Verify Integrity of Game Files

  5. Delete the Downloading Folder in SteamApps

    Make absolutely sure Steam is fully closed before deleting files in the SteamApps directory. Deleting files while Steam is running can cause additional corruption.

  6. Remove and Recreate the App Manifest File

    Do not delete the manifest file outright until you have confirmed the renamed backup resolves the issue, so you can restore it if needed.

  7. Run Steam as Administrator

  8. Temporarily Disable Antivirus or Firewall

    Only disable antivirus temporarily for testing purposes. Re-enable it immediately after confirming whether it was the cause, and add exceptions instead of leaving it off.

  9. Reinstall the Affected Game

    Back up any local save game files before uninstalling, as they may be stored in the game's local folder and could be deleted during uninstallation.

When to Call a Professional

Steam Error 1007 is almost entirely a software-side issue, so professional repair is rarely needed. However, if you consistently see this error across all games and Steam reinstallation does not help, the problem may be a failing hard drive or SSD where Steam is installed. In that case, run a disk health check using a tool like CrystalDiskInfo (Windows) or Disk Utility (Mac). If your drive shows reallocated sectors, pending sectors, or a health status of 'Caution' or 'Bad', consult a data recovery specialist or replace your storage drive before your data is lost. Additionally, if you believe your Steam account has been compromised or restricted by Valve, contact Steam Support directly at help.steampowered.com.

Frequently Asked Questions

Why does Steam say my library item is locked?
Steam locks library items when they are actively downloading, updating, or being verified. It can also happen if a previous Steam session crashed mid-update, leaving a stale file lock, or if game files have become corrupted. Restarting Steam completely and clearing the download cache resolves this in most cases.
Will I lose my game progress if I fix Steam Error 1007?
Most fixes for Error 1007 — like restarting Steam, clearing the download cache, or verifying game files — do not affect your save data at all. If you need to reinstall the game, saves stored in Steam Cloud are safe. For local save files, it is a good idea to back them up manually from the game's save folder before uninstalling.
Can Steam Error 1007 be caused by my antivirus?
Yes. Antivirus software, including Windows Defender, can place a hold on game files during or after an update scan, which prevents Steam from accessing them. Try temporarily disabling real-time protection and then adding your Steam and SteamApps folders as permanent exclusions in your security software to prevent this from recurring.
How do I find the SteamApps folder to delete the downloading folder?
On Windows, the default path is C:\Program Files (x86)\Steam\steamapps. On Mac, it is ~/Library/Application Support/Steam/steamapps. You can also find it quickly in Steam by going to Settings > Storage, clicking the three-dot menu next to your library, and selecting 'Browse Folder'. Make sure Steam is fully closed before making any changes inside this folder.
Does Steam Error 1007 mean my account is banned or restricted?
Not necessarily. Error 1007 most commonly refers to a file-level lock on a local library item rather than an account restriction. However, if the error persists only for one specific game after all troubleshooting steps, it is possible that your access to that game has been revoked (for example, if a Family Sharing session ended or a subscription lapsed). Check the game's status in your Steam Library and contact Steam Support if you believe there is an account issue.
