By default this program is included with DirectX 11 as well as other versions of the same distribution. If this element is missing from the system, users may encounter an error when starting some games.

Possible solution

The file might be damaged as a result of a virus attack or firmware failure. What is more, the library can become unavailable after installing unlicensed and pirated games or software.

It is named either System32 or SysWOW64, depending on the architecture of your OS. You can also place the component in the directory where the game is installed.

The next step is to run the command-line and register the dynamic link library. You have to enter regsvr32 d3dcompiler_43.dll and press Enter.
