Instead of using risky third-party software, you can usually fix DLL issues for free using built-in Windows tools:

Open Command Prompt as Administrator and type sfc /scannow . This repairs corrupted system files automatically.

Most missing DLLs (like msvcp140.dll ) are fixed by downloading the official packages directly from the Microsoft website .

If a specific game or program is throwing the error, reinstalling it usually replaces the missing file.

If you tell me the name of the missing file, I can give you the safe, official steps to fix it.
