The game runs. You lose ray tracing, but gain stability. If this works, the issue is your DirectX 12 setup, not the game files.

As a last resort, a clean installation may be required. Uninstall the game from your platform (e.g., Epic Games or Steam). Then, (e.g., ...\Epic Games\HITMAN3 ) and the entire C:\Users\[YourUsername]\AppData\Local\IO Interactive\HITMAN3 folder. This ensures no corrupted leftover configuration interferes. After a system restart, reinstall the game.

Sometimes the "Executable Not Found" error is literal—your antivirus has blocked or deleted the file.
