What is d3dx9_43.dll error and how to fix it

Any operating system is not immune to errors. Some of them are small, which have almost no effect on performance, and some can cause significant harm to your forwarding at the computer. In this article, we will talk about the d3dx9_43.dll error that pops up when you start a game or program.

Definition

Before embarking on ways to fix the problem, it’s worth initially telling you what the d3dx9_43.dll error is and why it generally occurs in the system.

So, it’s worth immediately explaining that any file with the extension .dll is a library. In turn, the library allows the operating system to interact with any components of third-party software. So, the d3dx_43.dll library is a component of the well-known DirectX 9 package that interacts with 3D models. It follows from this that an error related to the lack of the presented library can occur only in those cases when you are trying to run a program or game that has these same 3D models.

Continuing to figure out what the d3dx9_43.dll error is, it is worth saying that it is quite easy to fix it - you just need to register the library in the system. One of the options may be to install the very DirectX 9. Note that the ninth version is needed, since it has the necessary version of the library.

The first way: using DLL Suite

Having understood what the d3dx9_43.dll error is, you can go directly to the methods of solving it. This we will immediately do.

When the d3dx9_43.dll error occurs in the system, then you can fix it relatively easily. The first method will involve the use of a special program that is created specifically for such cases. The name of the software is DLL Suite, and if you are going to troubleshoot using it, be sure to download the program before proceeding with the instructions.

1. Run the program.
2. Go to the "Download DLL" category.
3. In the search box, enter the name of the library. In this case, it is d3dx9_43.dll.
4. Click on the "Search" button.
5. In the output of the results from the list, click on the desired library.
6. From the list that appears, select the version you need.
7. Click the Download button.
8. In the window that appears, pave the path to the desired directory (usually the correct one is specified by default).
9. Click OK.

After you have completed all the manipulations, the program will automatically download and install the library in the desired directory, and a green checkmark will appear next to the library you selected, indicating that the task has been completed.

The second way: using DLL-Files.com

The previous method, as you can see, is quite simple, and it should not cause problems for anyone, however, if the system still writes the error d3dx9_43.dll, you can resort to the second, slightly different method.

This time we will use the program DLL-File.com, so pre-download it on your PC and install. After that, to fix the error, you need to follow these steps:

1. Open the program.
2. In the first window in the search line write the name of the library. In this case, it's still the same d3dx9_43.dll.
3. Perform a search.
4. In the results, click on the library found.
5. Click the "Install" button.

In this case, even fewer points need to be performed. As a result, the desired library is automatically loaded and installed in the directory. After, run the application that previously threw an error.

Third way: using DirectX 9

At the beginning of the article it was said that the d3dx9_43.dll library is a component of the DirectX 9 package, therefore, to add it to the system you need to install this same package.

There is practically no difficulty in this, but there are many nuances. First of all, you need to download the package exclusively from the official site, since on unreliable sources there is a big risk of catching a virus. Secondly, it is important to download the ninth version of the package, because, as mentioned earlier, only it has the library we need.

1. In any search engine, write "download directx 9".
2. In the results, go to microsoft.com.
3. On the page that appears, select the language of your system.
4. Click "Download."

After the done manipulations, you just have to install the downloaded package in the system, after which the idle applications will open without problems.

Now you know what the d3dx9_43.dll error is and how to fix it, at least there are three effective ways to do this.
