While antivirus programs are the most frequent cause of this issue, other factors such as corrupted system files, incomplete game data, or interference from background applications can also contribute to the problem. Let’s discuss the solutions to tackle this issue.
1. Repair System Files
System files may become corrupted over time due to failed updates or sudden shutdowns. If the files required by Steam to function properly are damaged, it can hinder Steam’s ability to access the game files, leading to error code 53. In such cases, you can repair those corrupted files using the SFC (System File Checker) command. This command verifies and restores problematic system files by replacing them with a cached copy.
2. Disable the Antivirus Program
Antivirus programs occasionally flag legitimate processes as suspicious, leading to Steam error code 53 due to their overprotective mechanisms. Programs like McAfee and Avast often cause this error. However, if you have a different antivirus program, you should disable it as well. To do this, follow these steps (the exact steps might vary depending on your antivirus program):
3. Delete the App Manifest from the SteamApps
The manifest file stores metadata about the game, including update histories, installation details, and file paths. Deleting these manifest files will prompt Steam to regenerate them if they have become corrupted, potentially resolving error code 53. Before proceeding, ensure that Steam is closed.
4. Verify the Game Files
Verifying the game files ensures all necessary files are present in the game’s installation directory and are correctly configured. Corrupted or missing game files can prevent the game from launching, resulting in this error code. Here’s how to verify the game files:
5. Check for Background Applications
If multiple applications are set to run at startup, they could be interfering with Steam’s processes and preventing it from accessing essential game files. In this case, performing a clean boot can help identify which program or service is causing the interference. If the error persists, consider reinstalling both the game and the Steam application. This may help resolve the error if faulty Steam or game files are the cause.
