D3dx9_43.dll error: what to do and how to fix

For the correct launch of programs and games on the computer, the presence of all the libraries in the system is an important part, otherwise the applications will simply give an error. For example, in World of Tanks (WoT) d3dx9_43.dll is an integral component without which the game will refuse to start. By the way, the article will talk about this library.

Definition

Initially, we will talk about the d3dx9_43.dll error itself, what to do with it and how to fix it, we will tell later, because you need to know what we are dealing with.

So, the d3dx9_43.dll library is a component of the fairly widespread DirectX 9 package. In turn, this package is necessary for working with 3D graphics. In simple terms, without this library, the computer simply will not be able to interact with 3D models, and in order not to burden the unlucky user, the system scans the system at the start-up phase and generates an error if it does not find the required library. This error, as you might already guess, most often occurs when starting games, but in some cases programs will also refuse to work.

Few people know what to do with the d3dx9_43.dll error, however in this article you will find all the answers to the questions. And since we have already figured out the definition of this phenomenon, we can proceed directly to methods of eliminating it.

Method One: Download and Install DirectX 9

So, if you do not know what to do with the d3dx9_43.dll error, then the most logical solution is to download and install the DirectX 9 package, because, as mentioned above, it contains the necessary library that the game or program requires.

But there are pitfalls in this method, because you need to know what to download and how to install. For example, downloading a package from an unofficial site is highly discouraged, because the chance to infect a computer with a virus is quite high. But now an instruction will be provided in which everything will be disassembled in detail.

You need to download the package from the official site. In order not to look for it for a long time on it, it is easier to conduct a search in one of the well-known search engines. So:

1. Log in to the search engine.

2. Write in the search bar "download directx 9".

3. Perform a search.

4. Follow the link with microsoft.com address. It is very important that this link is there, as this is the official distribution site for this package.

5. On the page in the drop-down list, specify the language of the system.

6. Click "Download."

The download of the package will begin. After its completion, run the file and perform the installation. This is done quite simply, you need to agree to the license agreement, and then click Install.

This was the first way to fix the d3dx9_43.dll error, but maybe it will seem rather complicated to you, or you may simply get stuck on some point, so let's move on to the second method.

Method Two: Using DLL Suite

You already know what to do with the d3dx9_43.dll error, but here is the second solution to the problem. it implies using a program called DLL Suite. This is a fairly simple and convenient tool for solving problems with the lack of libraries. Before following the instructions below, download and install this program.

So, to fix the error you need to do the following:

1. In the first window of the program go to the category "DLL Download".

2. In the search line, enter the name dll, and then click the green "Search" button.

3. In the results that appear, click on the desired library.

4. In the expanded list, click "Download" opposite the desired version of the dll.

5. In the window that appears, specify the path to the directory where the library should be installed. The System32 folder is selected by default, and it is the right one for most cases.

6. Click the OK button.

After completing all the items, downloading and installing dll will begin. After successful completion, a green checkmark will appear next to the selected version of the library, indicating the successful completion of the installation process.

Method Three: Using DLL-Files.com

If for some reason the previous program did not help you, then you can use the analogue - DLL-Files.com. This method will even be simpler than the previous one, since there are much fewer points in it. So, just like last time, download and install the program on your computer, launch it and follow these steps:

1. In the search box, enter the name dll.

2. Click the "Search Now" button.

3. In the results, click on the option.

4. Click the Install button.

That's all, only four points, after which the necessary library will be installed on your computer. Once the installation process is complete, you can run your program or game, which previously refused to do so.

Fourth method: manual installation of dll

If you have already tried all three of the previous methods, but the system still knocks out the d3dx9_43.dll error, then the last hope remains - to install the library yourself. This is done quite simply, but there are some nuances:

1. You need to download the library from the Internet. Now many sites are happy to provide the ability to download it, but pay attention to its transparency and do not download the file from an unreliable source, as often attackers spread viruses in this way.

2. After downloading the dll, first check it for viruses, using some kind of anti-virus software.

3. Move the downloaded library to the System32 folder, which is located on the path C: \ Windows \ System32.

After that, the problem should disappear. Sometimes moving the file to the SysWOW64 folder also helps, which is located on the same path.
