A Dynamic Link Library or DLL is a file that contains codes and resources that a program uses to execute certain functions. Other programs or applications can use and share the DLL file. There are different kinds of DLL files, and the DirectX 9 DLL is just one of many. DirectX works like a set of drivers that programs need in order to run. A program may need a group of specific drivers so it can perform specific functions, so DirectX becomes the interface between the program and the different drivers. Mostly game programs use the DirectX to run functions for graphics, video, sound cards, game controllers, and network gaming. There are problems that arise when using DirectX; some versions will only work for specific programs. So if you have a new game that requires installing DirectX 9 DLL and you install another game that is older and uses and older version, the DirectX 9 DLL may be overwritten by the older one. That’s why if you run the previous game that needs the newer version you will get an error message warning you that it did not find the DirectX 9 DLL that it needs to run. If DirectX 9 DLL is missing, you can reinstall a copy on your computer.

Many programs require specific versions of DirectX; some may use old versions if it is an old program. Installing these old programs may delete your current version of DirectX. Do a search first of your computer before downloading a copy.
