  2. When reinstalling, choose a file path that is short and contains no special characters.
    • Bad Path: D:\Games\Lara's Adventure\Rise of the Tomb Raider
    • Good Path: D:\Games\ROTTR
  3. Avoid installing the game directly to the Program Files folder if you are having permission issues; try installing it to a separate drive or a simple folder on the C: drive.

Causes of the Error

Before diving into the solutions, it helps to identify the likely culprit. The most common causes include:

  1. Special Characters in File Paths: If your Windows username or the installation folder contains special characters (like accent marks, tildes, or symbols), the game engine often fails to parse the path correctly.
  2. Antivirus Interference: Security software may falsely flag the large data files as suspicious and quarantine them or block read access.
  3. Corrupted Game Files: A bad download, an interrupted update, or a hard drive error can result in a corrupted bigfile.000.
  4. Lack of Administrator Privileges: The game may not have permission to read files in the installation directory.
