How to fix missing d3dcompiler_43.dll file error

Hello. I often get help from gamers who, after launching some game, saw a notification on the screen that the program stopped working because d3dcompiler_43.dll is missing. What kind of error it is and how to fix it in a matter of minutes – I will tell you about it in this review.

Subject of the problem.

“Failure” can appear in any version of the operating system Windows. The cause is a damaged or missing component from the set of DirectX libraries. Here are the file properties proving my words to be true:

File description d3dcompiler43

This item is a compiler necessary to run a full-fledged game application. By default it is located in one of the system folders:

Windows | SysWOW64

Windows | System32

The first one is present only in Windows 64 bit. By the way, you need to know the bit mode of your operating system to proceed. This is easy to do – here are the instructions.

Very rarely, the file d3dcompiler_43.dll is missing specifically in the directory with the game, which at start-up gives an error:

You may have already completed downloading the missing library and do not know what to do with it next. Just copy it into the above folders is a logical solution, but not quite right. The thing is that there may be many such files. One you put in the right place, but when you open the game a new error will appear due to the absence of another file from the DirectX set.

And you can spend a lot of time to find all the necessary objects. Let’s not engage in such “masochism” and do everything quickly and beautifully.


Update from Microsoft official site

When you install Windows, it comes with some of the dynamic libraries needed for the game programs. But, alas, sometimes they are not enough, or their versions do not correspond to those required for the game.

To download d3dcompiler_43.dll for free along with other important components, just download the web installer to your PC from the Microsoft website:

Download

If the link does not work, then go to the application page, specify the Russian language and just click on the download button:

Download directx set

Why is upgrading the best option? When you run the DirectX installer, it detects the bit-size of the system, downloads only the necessary elements from the server, arranges them in their places. You just have to restart your computer.


Manual installation

Just in case you decided not to listen to my advice and want to download d3dcompiler_43.dll for Windows 7 (or any other version) separately, here are the links for the right bit type of OS (how to determine it – here)

DLL-Helper

  • After unpacking the archive, you need to copy the library file to one of the folders I wrote about at the beginning of the article.
  • Be sure to register in the system, so that Windows can “see” the new components. To do this, start a command line with administrator privileges (all the ways are described here) and run the command:

regsvr32 d3dcompiler_43.dll

There is a chance that after you press Enter to run the command, an error will be displayed. This tells you that this version is not suitable for your OS. I would advise you not to bother, and go straight to the automatic update, about which I wrote a little above.
