The d3dx9_43 error may occur to you if something happened to the library specified in the error message. This error message says:
The program cannot be launched because d3dx9_43.dll is missing on the computer (no matter what d3dx9 number is indicated in the error). Try reinstalling the program.
So what reasons could lie behind this? In fact, there are not so many of them. The library might not be registered, damaged, or missing altogether. Let's figure out how to fix this problem.
Solution to d3dx9_43.dll error
Method No. 1
One of the most obvious solutions would be to simply take and install the package with libraries DirectX. This will most likely solve your problem right away. You can download DirectX directly from the official Microsoft website.
Method No. 2
The next, not the most convenient, solution would be to download the missing library yourself. Then put it in the root folder of your system: C:\Windows\System32\ or C:\Windows\SysWOW64\. Then you need to register this file. To do this, click Win+R and enter the command in the window that opens regsvr32.exe C:\Windows\System32\d3dx9_43.dll or C:\Windows\SysWOW64\d3dx9_43.dll
Greetings!
This article will primarily be dedicated to avid fans of computer games who encounter problems when launching them.
The most common reason why the game does not start is the lack of the latest version of DirectX in the Windows operating system. As a result, when you try to start the game, a message pops up with the following content: “The program cannot be started because the file is missing on the computer d3dx9_xx.dll. Try reinstalling the program." Moreover, very, very many games use DirectX components in their work - this can be either the well-known World of Tanks game or a little-known indie game.
It should be noted that the file name indicated in the error text may have a different ending: d3dx9_ 26 .dll … d3dx9_ 43 .dll .
All this suggests that your system does not have D3DX9 (DirectX), or the existing version is outdated and requires an update.
These problems arise especially often after the recent installation (reinstallation) of the Windows 8 (8.1) and Windows 10 operating systems.
In order to correct this situation, this material was prepared. It will tell you in detail how to install or update DirectX, thereby getting rid of errors when starting the game.
How to update DirectX - a method that does not require Internet access
In the absence of Internet access, installing and updating DirectX is somewhat difficult.
The easiest way is to take the disc with the game you already have and during the installation process, check the box for installing add-ons, which quite often includes DirectX. You can subsequently delete the game itself - the installed or updated DirectX will remain in the system.
You can also use a utility whose task is to update drivers. It often contains the latest updates for DirectX.
Updating DirectX via the Internet
In this situation, the task is significantly simplified.
You can download the official installer distribution from the developer's website. To do this, follow the link http://www.microsoft.com/ru-ru/download/details.aspx?id=35 and after making a few clicks, download it.
After it is completely downloaded to your computer, run it.
After a short system check, you will be prompted to install or update DirectX - agree and click Further.
The time to install or update the necessary components primarily depends on the speed of your Internet connection. the corresponding files will be downloaded directly from the Internet from the Microsoft website.
On average, installation time is 3.. 7 minutes.
After installing or updating DirectX components, the problem with the error about missing files “d3dx9_xx.dll” (xx is a block of numbers, may be different) should disappear.
What to do if the DirectX error does not disappear - d3dx9_xx.dll file is missing
Did your DirectX installation fail? Some DirectX components have not been updated? Or maybe everything went well, but the error still occurs? This usually indicates problems with the installed operating system.
Undoubtedly, reinstalling the operating system could solve the problem, but this is not always acceptable.
In this situation, you can do the following:
Underline the file name that is missing to successfully launch the game. And then, using an Internet browser, find and download this file on the Internet.
However, you must remember that the downloaded file must only have the extension dll, but not exe. Otherwise, you risk installing some malicious or adware application.
But even if you downloaded the required dll file and checked it with an antivirus, there is still a possibility that it will be an old version and the game will either refuse to work or the gameplay will malfunction.
However, he will not tune in to a negative scenario. Having received and checked the desired file, you will need to copy it from the Windows system folder (directory).
By default, in all versions of Windows, the path to this folder is as follows:
for 32-bit systems
C:\Windows\System32
for 64-bit
C:\Windows\syswow64
If in doubt, copy the downloaded file(s) to both folders - it won’t get any worse.
After copying the file and launching the game, an error may be displayed in which another missing “d3dx9_” will already be indicated xx.dll" ( xx– block of numbers, may be different) – then repeat the procedure with searching and copying this file.
Brief summary
In this material, we examined in detail the reasons for the appearance of common errors that occur when launching games on a computer. We looked at the process of installing DirectX components in order to cope with the error indicating the absence of the “d3dx9_xx.dll” file (xx is a block of numbers, may be different).
If you have any questions, you can ask them in the comments.
The error about the missing d3dx9_43.dll file in the Windows operating system most often occurs when you try to launch a game or other application that uses the DirectX graphics subsystem. We understand the causes of the problem, as well as ways to fix it.
d3dx9_43.dll is missing on the computer: what does the error mean?
An error like “d3dx9_43.dll is missing from the computer, the program cannot be launched” is a consequence of the lack of installed DirectX version 9 library (this version of the API was released with Windows XP and is mainly used in older games and applications).
This library is an implementation of the Microsoft API for low-level operation of programs with computer hardware resources. Simply put, with its help, a program or game will be able to “correctly” access the sound card, video accelerator and input/output devices (including the gamepad).
Can this error occur on Windows 7, 8, 10? Yes, even if DirectX above version 9 is already installed on your computer. To support older applications and games, you will need to install all versions of the API.
Causes of the problem
Most often, the error indicates that the operating system was recently installed and DirectX has not yet been installed.
The lack of a library included with Windows is due to the fact that some patents of manufacturers of graphics processors, sound cards and HID devices may be violated. That is, this is a purely legal formality.
Also, a problem related to the d3dx9_43.dll library may occur in the following cases:
- damage to the hard drive (the appearance of “bad” sectors when the information recorded on them is erased);
- the DirectX library has been replaced (this happens if you try to install an outdated version of the API, for example, DirectX 8);
- damage to the OS by viruses (they often replace system libraries with third-party DLL files into which malicious code is embedded);
- problems with the registry - for some reason the DirectX library is not registered in it (although the d3dx9_43.dll file itself is present in the system);
- Outdated drivers are installed for the sound card, graphics accelerator, HID devices (DirectX support for devices is implemented through drivers).
How to fix the error
It is not always possible to determine the exact cause of the error, so you will have to try all possible methods to eliminate it. First of all, it is recommended to scan the system partition for viruses, then try to register the library using the command line. It’s also worth trying to clean the registry and update the drivers (in particular, the sound and graphics cards). And if DirectX has not been installed previously, you should download it from the official Microsoft website and install it.
Virus check
Even if the d3dx9_43.dll file is present on the system disk (it is located in the C:\Windows\System32 directory), it is quite possible that it was replaced by a damaged or virus-infected file. And, by the way, such virus programs quite often replace several libraries at once, disrupting the operation of the operating system. Therefore, you should start by checking your computer for viruses.
Windows 7 has a built-in Microsoft Security Essential antivirus program by default (Home Premium and higher editions). If it is not in the list of installed applications (in Windows 8, 8.1, 10 it is called Windows Defender and is already integrated into the system), then you will first need to download it from the official website (windows.microsoft.com/ru-RU/windows/products /security-essentials) and install. The utility is provided free of charge.
After installation you will need:
If for some reason the user does not want to install an antivirus from Microsoft, then you can use the free Dr.Web CureIT! utility. You can download it from the official website (free.drweb.ru/download+cureit+free/?lng=ru).
You can check your computer using the free Dr.Web CureIT! The key feature of the CureIT utility is that there is no need to install it. At the same time, the program allows you to scan not only the system partition, but also all installed hard drives.
Registering a library via the command line
This action will help if for some reason the DirectX library was not registered in the registry (software error or OS malfunction).
Algorithm of actions:
Removing and restoring a library
If DirectX was previously installed on the PC, but during the automatic system update any problems arose (for example, there was no Internet or the update process was interrupted), then this may lead to the fact that a simple solution to this problem is to remove and repeat restoration of the library.
This is done as follows:
Cleaning the operating system registry
This library also causes problems in the registry. It is quite possible that the user tried to install DirectX several times and after each attempt, entries about the installer remained in the registry, but the API set itself was not in the system. The same will happen if any errors occurred during the DirectX update or the process was not completed.
The easiest method of cleaning the registry is to use. You can download it from the official website (ccleaner.com), you should choose the Free version.
After installing the program, perform the following steps:
Driver Update
Windows 10 automatically downloads all missing drivers, as well as all future updates for them. So, owners of this OS just need to enable system updates - then Windows will do everything itself.
But in older editions of Windows, installing and updating drivers must be done manually. A simpler option is to use special utilities to automatically search for and install missing drivers. One of these is DriverDoc. You can download it from the official website (driverdoc.com/index.html), but for its full operation you will need to purchase a license.
To update drivers using standard Windows tools you will need:
Even if this does not help solve the error problem, you must constantly install the latest versions of drivers for your PC. It is recommended to carry out this operation at least once every 2–3 months.
Downloading and installing DirectX
It should be downloaded exclusively from the official Microsoft website (microsoft.com/ru-ru/Download/confirmation.aspx?id=35).
The library's web installer will be saved to your computer. All you have to do is launch it and follow the instructions on the screen. By the way, if the user has DirectX version 10, 11 or 12 installed, the installer will independently check which libraries are missing and install them automatically. Once the installation is complete, be sure to restart your PC.
The latest versions of DirectX check on their own which libraries are present and which are missing This recommendation applies to all versions of Windows, including the outdated (and no longer supported by the manufacturer) XP. For the web installer to work, you must have access to the Internet, since during the installation process it will download all the missing libraries (on average, it will require from 10 to 20 megabytes of traffic, the installer itself takes up less than 1 MB).

What to do to prevent the error from occurring again
To prevent the error about the absence of the d3dx9_43.dll file from appearing on your computer, you should:
- enable automatic system updates (the Windows Update service must also be running);
- install DirectX using the web installer (it installs the latest version of the library);
- use the built-in Windows Defender antivirus or Microsoft Security Essential;
- regularly update drivers for all installed devices (in particular, sound card and graphics adapter);
- use only licensed software and Windows (so that automatic updating works, since pirated copies of Windows do not have this feature or only partially function).
There are many options for eliminating the error associated with the absence of the d3dx9_43.dll library. By following step-by-step instructions and recommendations, you can solve the problem yourself and prevent it from recurring in the future.
D3dx9_43.dll is an essential component of DirectX 9, without which you will not be able to run some games and programs. Many users, after installing Mass Effect, World of Tanks, or other games and programs, see the error “D3dx9_43.dll is missing” or “D3dx9_43.dll not found.” Then a long search for this file on the network begins, which does not always end successfully. Someone is trying to download the D3dx9_43.dll file from a dubious site and then simply copy it to the C:\Windows\System32 folder. However, this option will get you nowhere.
“But why do I need DirectX 9?” you may object. Without a doubt, your computer probably has DirectX 11. And if you use Windows 10, then DirectX 12. This is not enough when the system lacks some libraries from previous versions of Direct X. And your favorite games simply won’t start.
In the instructions below, we will tell you in detail how to fix the error that has arisen. By the way, this problem appears in Windows 10, Windows 8 and Windows 7.
Step by step guide where to download D3dx9_43.dll
In order for the necessary .dll libraries to appear on your computer, you will need the Microsoft installer. It will add the necessary file to the system that corrects the error “Cannot start, d3dx9_43.dll is missing.”
- To download the dll for Windows, as well as other additional DLLs, follow the link to the official website. Here you will be able to download the web installer.
- Run dxwebsetup.exe. When prompted to install additional software, uncheck the boxes (it suggests installing the Microsoft Bing panel). We agree to the terms.
- Wait until the installation completes. In automatic mode, the program downloads the missing files for the library.
- After the message “Installation Complete” appears, try to launch the game or program that did not work before again. The message that D3dx9_43.dll is missing will no longer appear.
Second option:
- Download the archive with the d3dx9_43.dll file from our website.
- Copy the file from the archive to the folder C:\Windows\System32. If you have 64-bit Windows, then you need to put the file in the System32 and SysWOW64 folder.
Everything should work out.
Hello to all gamers and just guests of my blog!
In this article I want to talk about a very common error: the absence of the d3dx9_43.dll library, and the simplest method for solving it.
Very often, when launching new games downloaded from the Internet, you can stumble upon this error. Due to the fact that these games do not have DirectX built in. In fact, you don't need to download d3dx9_43.dll separately. This will not solve the problem, everything is much simpler, dear friends, you need to update DirectX, I wrote in this article how to do this quickly and correctly.
many errors, one solution! Download!
Let's take a closer look at the D3DX9 43 dll error, the fact is that the number after D3DX9 43 can be anything; D3DX9 41 dll, D3DX9 42 dll, etc. This is simply the library number that the system is looking for to launch the game. Once again, do not search for this file on the Internet by typing “D3DX9 43 dll download”, this will not solve the problem, but will only add - you download D3DX9 No. 42, the system will ask for D3DX9 dll No. 43 and so on. All these files are built into DirectX and when you install it, this error will no longer appear, which I will talk about in more detail later.
Attention! This is the most common error on a computer, but there are still often problems with OpenAl, it’s better now than to look for it later.
Solving the D3DX9 43 dll error, updating DirectX
To update we will need the Internet, but if you read this article I think you have it. Next, we do everything according to the instructions.
If you don’t want to bother, then download DirectX from the link below, immediately after it there is a link to the official website.
1) from my website.
When I clicked the download button, I got this window asking me to update system components and applications. Decide whether you need the super browser Internet Explorer, or other “hits” from Microsoft, I decided not to update anything.
2) After launching DirectX, we accept the license agreement.
3) Don’t forget to uncheck the box; we don’t need extra panels in the browser, especially from the Bing search engine.
4) The update process will begin, I did not have this window, since I have the latest version.
5) The program will update DirectX, and you no longer need to search for the D3DX9_43.dll library separately. We just installed it. Now all games will run without D3DX9 errors, and when you launch the DirectX web installer you will see a window like this.
