It seems you're looking for (DirectX Control Panel) for Windows 7 64-bit , possibly related to a version number (37) or a file with that label.
Windows 7 is natively compatible with DirectX 11, but many older games and applications still rely on (which is where the version numbers get tricky).
: If you installed the SDK but can't find the tool, ensure you have .NET Framework 3.5.1 enabled in "Windows Features".
