If the installer remains stubborn, the user must turn to system-level diagnostics. Windows 7’s built-in System File Checker ( sfc /scannow in an elevated command prompt) can repair corrupted Windows system files that interfere with the installer’s engine.

Without these, the operating system will reject the installer’s digital signature outright, misreporting it as damaged.
