  2. Right-click Shadow of the Tomb Raider → Properties → Installed Files.
  3. Click Verify integrity of game files.
  4. Wait for the scan to complete (it will re-download missing/corrupt files).
  5. Restart Steam and try launching the game.

5. Clear Steam download cache

Method 2: Run Everything as Administrator (The Permission Fix)

The "Failed to initialize Steam" error often appears when the game tries to hook into Steam using standard user permissions, but Steam is running with elevated permissions (or vice versa).

You need to force synchronization.

  1. Navigate to your Steam installation folder (usually C:\Program Files (x86)\Steam).
  2. Right-click Steam.exe > Properties > Compatibility tab.
  3. Check "Run this program as an administrator." Click OK.
  4. Now, go to your Shadow of the Tomb Raider install folder.
    • Default: C:\Program Files (x86)\Steam\steamapps\common\Shadow of the Tomb Raider
  5. Right-click SOTTR.exe > Properties > Compatibility.
  6. Check "Run this program as an administrator." Click OK.
  7. Launch Steam. It will ask for permission; click Yes. Then launch the game.

Warning: Running Steam as admin permanently can break drag-and-drop mod installations. After fixing the error, you may revert Steam to normal, but keep SOTTR.exe as admin.

Steam installation & library issues

  1. If the game is installed on an external drive, try moving it to the main internal drive (Steam → Properties on the game → Local Files → Move install folder).
  2. Repair Steam library: Steam Settings → Downloads → Steam Library Folders → right-click the folder → Repair Library Folder.
  3. If Steam installation is damaged, back up steamapps/common, uninstall Steam, reinstall, then restore the steamapps folder (avoid overwriting userdata).

The Steam "Bootstrapper" manages the client’s core logic. If it is corrupted, nothing will connect to it correctly.

  1. Exit Steam completely (right-click tray > Exit).
  2. Press Windows Key + R, type %appdata%, and hit Enter.
  3. Find the Steam folder. Delete only the following files (do not delete folders):
    • appcache.vdf
    • steamapps.vdf
    • steamclient.vdf
  4. Now navigate to %localappdata% (paste it into the Run dialog).
  5. Find the Steam folder. Delete htmlcache and depotcache (if they exist).
  6. Restart your PC. Steam will rebuild these files upon launch.
