d3dx9_43.dll Missing Error : What the Particular DLL Does
d3dx9_43.dll is the newest of the DirectX 9 files and does not install with Windows 7 but later version of Microsoft Windows. We denote these DLL as
d3dx9_xx.dll. The value of
xx varies with version of DirectX and Windows version.
Missing error usually appears when the user try to start a high-resolution graphics games. It can occur on any Windows OS version, but it is reported more on the Windows 10 v1703 and v1709. In many cases, it happens soon after the installation of the latest OS update. The d3dx9_43.dll file is not a crucial part of the Windows OS. It belongs to the library which is responsible for launching Windows–based games and advanced graphics programs.
It is practical to check Display Adapters section from device manager and click to check status of graphics driver (like Intel HD Graphics driver). Often that graphics driver become missing on Windows 10 along with DLL error.
Why Is It Risky To Download DLL File From Unknown Sources?
There are several reasons for it.
- Typically, when the user faces such a bug, he or she immediately begins to look for where to download this library, although this is the easiest way to get viruses to your device and, more than likely, it will not fix the bug. That is, you get the library documents from a doubtful site among which there are even groups in social networks, sites with bug names, etc.
2. At the same time, you do not know what is there, since any such library can contribute whatever you can think of.
3. You register this element in the OS and such actions bring consequences. Well, with a purpose to avoiding such situations, it is enough to know what the DLL file is for, what kind of an element it is, and just install what is needed.
The DLL Elements Are DirectX Libraries, And Therefore It Should Be Installed
It is possible that the game or app lacks not only one DLL element but several library files. If you download only a specific document and register it in the OS, there is a high probability that a new bug will occur and similar actions will have to be repeated several dozen times.
One of the most popular forms of fraud is the infection of such files with viruses. When installing games and apps, it is often suggested to install or re-install DirectX (depending on the situation). Never refuse this procedure, then you can avoid an error showing that there is no some element of the software.
So, if the program cannot be started due to the specified files, it is guaranteed that there are not necessarily enough (usually for the game) elements of DirectX. So, you do not need to download separate elements; you just need to install the program, which will automatically set all the necessary libraries in the system. Following that messages that some DLL file is missing will not appear again.
There are two ways how to get DirectX for this purpose. You can use Microsoft’s Web Installer for Windows 7 and 8 or a separate installation program for Windows XP or simply install from the official DirectX site, and the error will be fixed.
Again, official answer from Microsoft is to download and run the DirectX End-User Runtime Web Installer on your computer and then try to start the game/program which was throwing the error.
