Error: 'FILENAME'.DLL is Missing / not Found

A DLL is a library that contains code and data that can be used by more than one program at the same time.  If you are getting an error stating a certain DLL is missing, then this means that file has become corrupted or deleted.

A good first step to resolving this is reinstalling the software – in most cases- the game.


Below are some common errors

  • D3dx9_43.dll Not Found
  • D3dx9_43.dll is Missing
  • Xinput1_3.dll not Found
  • D3D8.dll
  • X3DAudio1_7.dll

These errors are saying that there is a piece of DirectX that is missing. (DirectX is a Microsoft Program that determines the hardware capabilities of your computer, and then sets the program parameters to match.) To resolve those errors, reinstall Direct X from Microsoft

You will also need to make sure that Internet Explorer (even if it isn't your main web browser) is up to date. Internet Explorer

They can determine if there is a solution available. Be sure to include the OS your current computer is on, as well as what game you are seeing this error with.
