Steam Guide for the Missing Executable error

This error message will pop up when the game file is missing or is being blocked by another program. Here's what you can try to fix it:

Check your anti-virus software 

Missing Executable error is most commonly seen when your anti-virus software is mistakenly blocking game files. Here's how you can solve this:

  • Within the anti-virus software look for game files that have been reported and mark them as safe
  • Set your anti-virus software to Game Mode
  • Have the anti-virus software exclude that game folder when it scans for malicious content.

Verify Game Files

It's possible that the error message is not caused by anti-virus software and instead your game files are corrupted or failed to install properly. Simply restart your PC and verify your game files. 

  • Right-click on the game in your Steam library
  • Go to Properties then Local Files.
  • Click Verify Integrity of Game Files.
