It happened to you that you installed some kind of computer game and, anticipating the passage of the game process, start it, and the system suddenly displays a message that d3dx9_43.dll is missing on the computer? Many are looking puzzled at the screen and do not know what to do. The most important thing is not to panic, because this error is one of the most common and can be eliminated within a couple of minutes.
What is the d3dx9_43.dll object?
Before taking any action to fix the problem, let's see what kind of file it is, due to the lack of which the operating system or game begins to swear.
In fact, it is one of the important dynamic libraries that are part of the DirectX package, which is mandatory in all Windows systems (in our case, this is the ninth version). But the user can object, they say, how so? The DirectX platform is both installed and constantly updated, and the system writes that something is missing. Yes, indeed, this situation arises very often, and the library itself could be accidentally deleted, damaged, or even infected with a virus. That is why neither the system nor the installed game can recognize it correctly, as a result of which a notification appears that d3dx9_43.dll is missing on the computer. You can fix the problem with at least three basic methods, but let's start with the most difficult, although not the most effective.
Error "d3dx9_43.dll is missing on the computer": what should I do?
Typically, when errors occur, the average user does what? He turns to some search engine and looks for answers to his questions. And as recommendations, you can often find tips on downloading the original file to your computer from the Internet and then copying it to the desired location.
This technique has several disadvantages. Firstly, you cannot be completely sure that the resource from which the download is performed does not contain viruses. Secondly, the bit depth of the library may not correspond to the architecture of the operating system installed on the computer. Thirdly, it is not enough just to copy the downloaded file to the desired location on the hard drive - you need to register it.
But let's assume that you decided to get rid of the error in this way and downloaded the file of the required bit depth from a trustworthy site on which there are no viruses. After placing the original object in the folder with DirectX components, you need to register it.
To do this, start either the task in the Run console or the command line (exclusively on behalf of the administrator) and use the regsvr32 tool, and after the main command enter either the full path to the library being registered or simply enter the file name.
Note: when specifying the file path, be careful, since on 32-bit systems it should be in the System32 directory, and on 64-bit systems, it should be in the SysWOW64 folder.
The disadvantage of this technique is that no one can guarantee that the problem will not be repeated with any other similar library. In addition, if there is a bit mismatch or if viruses are detected, when the file is quarantined, the message that the d3dx9_43.dll object is missing on the computer will appear again.
Using the DLL Suite Automated Tool
As can be seen from the above, the first method looks rather cumbersome. Therefore, if the system reports that d3dx9_43.dll is missing from the computer, it is easier to fix the problem by using a specialized utility called DLL Suite. This program is just a universal tool that allows you to identify missing system files without user intervention, and after scanning is completed, download them from the Internet and integrate into the system.
By the way, the latest modification of this application in the form of the ninth version allows you to get rid of not only problems associated with missing DLL components, but also fixes errors with system files of EXE and SYS formats, as well as with their keys in the registry.
Not found d3dx9_43.dll: a complete reinstall of DirectX
Finally, we consider the simplest and at the same time cardinal actions regarding the elimination of a problem. How to fix d3dx9_43.dll error? Apparently, many have already realized that the easiest way is to visit the official website of Microsoft Corporation, download the DirectX installation distribution kit from there (in our case we are talking about the ninth modification, which is clearly indicated by the name of the missing component), and then simply install the platform again.
It is not necessary to download the full package, because if you have an uninterrupted Internet connection, you can use a special web installer. Its file on disk will occupy a minimum of space, and all necessary files will be downloaded during the installation process.
