The Solution (The Fix)

The most reliable fix involves creating a specific file in the game directory that forces the game to recognize the Steam App ID.

How to apply it:

  1. Navigate to your game installation folder (usually C:\Program Files (x86)\Steam\steamapps\common\Shadow of the Tomb Raider).
  2. Look for a file named steam_appid.txt. (If it doesn't exist, you must create a new text document and name it this).
  3. Open the file with Notepad.
  4. Ensure it contains the number: 750920 (This is the specific ID for Shadow of the Tomb Raider).
  5. Save and close the file.
  6. Crucial Step: Launch the game by double-clicking the Shadow of the Tomb Raider.exe directly from the folder, OR launch via Steam while running Steam as Administrator.

Fix 3.2: Delete config.vdf

This file tells Steam which games you own and their installation paths. A corrupted version breaks the API handshake.

  2. Open Windows File Explorer and paste this into the address bar: %SteamInstallationFolder% or navigate to C:\Program Files (x86)\Steam
  3. Find the file named config.vdf .
  4. Rename it to config_old.vdf (do not delete it yet, just in case).
  5. Restart Steam. It will generate a fresh config.vdf.
  6. Launch the game.
