Fixes of the error “There is no d3dx9_43.dll on the computer” when starting the game or program
In order not to look for where to download d3dx9_43.dll for free and not to download malware onto a computer or laptop, it is useful to ask the question: what is this file?
The answer is that this file is part of the DirectX 9 components needed to run many of the not-so-new games and some application programs.
Must be located in the C: \ Windows \ System32 folder (but do not rush to copy the downloaded d3dx9_43.dll from there).
Usually, the user reasons: but I also have DirectX 11 installed in Windows 7 or 8, or even DirectX 12 in Windows 10, but this is not enough.
By default, the system does not contain libraries (DLL files) of previous versions of DirectX, and they are necessary some games and programs.
And in order for these libraries to appear, it is enough to use the official installer from Microsoft, which will automatically add them to the system, thereby correcting the error “The program cannot be started because there is no d3dx9_43.dll on the computer”.
The next, not the most convenient solution is to load the missing library yourself. Then drop it into 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 regsvr32.exe C: \ Windows \ System32 \ d3dx9_43.dll or C: \ Windows \ SysWOW64 \ d3dx9_43.dll in the opened window
Download d3dx9_43.dll from the official site
In order to download d3dx9_43.dll for Windows 10, 8 and Windows 7.
As well as other DLL files that may be required to run a game or program that does not start (and most likely.
This requires not only this file), do next steps:
Go to the official Microsoft page https://www.microsoft.com/en-us/download/details.aspx?id=35 and download the DirectX Web Executable Installer for the end user.
Run the downloaded executable file dxwebsetup.exe. Agree to the terms and refuse to install additional software (at the current time it offers to install the Microsoft Bing panel).
Wait until the installation is complete: the program will automatically download all the missing (old but still up-to-date) Microsoft DirectX libraries.
Is done. After that, the d3dx9_43.dll file will be in the correct location (you can verify this by going to the C: \ Windows \ System32 \ folder and searching there), and the error stating that this file is missing should not appear again.
Why it is not necessary to download d3dx9_43.dll and other libraries from download sites
As mentioned above, the majority of users, instead of finding out what the DLL is required and what components it is a part of, are looking for a way to download it separately, finding.
As a result of a lot of sites specifically “honed” for such users.
Such a course of action is erroneous for the following reasons:
The site may be malware, or simply “dummy file” with the desired name, but without the necessary content. The latter option can confuse, lead a user who knocks on the keys “regsvr32 d3dx9_43.dll” to the wrong decision that it is time to reinstall Windows, etc.
Even if you know where to throw this file and how to register it in the system, this will most likely not correct the launch error: the program will simply inform you that it needs some more file (because games using DirectX require far from one dll of it).
This is simply the wrong approach, which in the future will surely result not in solving the problem and correcting errors, but in creating new ones.
That’s all. If there are questions or something does not work as expected – leave a comment, I will try to answer.
