"Unknown File Version" When I try and boot up Halo Master Chief Collection

The "Unknown File Version" error you're encountering when trying to boot up the Halo Master Chief Collection can indicate a problem with the game's files or installation. Here are some steps you can take to troubleshoot and resolve the issue:

1. Verify Game Files:
If you're playing the game on Steam, you can use the built-in file verification feature to ensure that your game files are intact. Right-click on the game in your Steam library, go to "Properties," then the "Local Files" tab, and click "Verify Integrity of Game Files." This will check and replace any corrupted or missing files.

2. Update the Game:
Make sure you have the latest updates installed for the Halo Master Chief Collection. Check for updates through the game's launcher or the platform you're using (Steam, Microsoft Store, etc.).

3. Reboot Your PC:
Sometimes, a simple reboot can resolve issues related to game files or processes that might be interfering.

4. Clear Cache and Temporary Files:
Clear any temporary files and cache on your PC. You can use the built-in disk cleanup tool or third-party software to do this.

5. Disable Mods:
If you're using mods for the game, they could potentially be causing conflicts. Try disabling any mods and see if the issue persists.

6. Run the Game as Administrator:
Right-click on the game's shortcut or executable and select "Run as administrator." This ensures that the game has the necessary permissions to access and modify files.

7. Check Antivirus and Firewall:
Your antivirus or firewall software might be blocking or interfering with the game's files. Temporarily disable them and see if the issue is resolved.

8. Repair or Reinstall the Game:
If the issue persists, you might need to repair or reinstall the game. Follow the instructions provided by the game's platform (Steam, Microsoft Store, etc.) for repairing or reinstalling games.
