Solution 1 Install DirectX
This exact DLL file belongs to DirectX. As you might know, DirectX is a bundle of different applications linked to multimedia and game programming.

And thats exactly why youre prompted with this error. One of the essential DirectX files is missing from the System32 folder and youll need to get it back where it belongs.
Firstly, we strongly advise you to avoid DLL-download websites. Avoid them like plague. Some of them might indeed provide proper DLL files, but the risk of malware is too high.
Now, if theres one Windows game-related redistributable that can be found everywhere, its DirectX.
You can navigate to the installation setup of any given game you have in your possession and it should be there.
From there, just run the installer and update DirectX. You can aim for the latest version, but thats not of immense importance. Any DirectX is better than none.
Otherwise, you can download DirectX from the official Microsoft site.
Solution 2 Reinstall the problematic program or game
Sometimes, the problem may lie in the game or application youre running, rather than in DirectX.
Such complex programs can easily get corrupted or can suffer from repetitive incomplete files.
On top of that, if we assume that other games or applications are working, its simple to conclude whats the culprit.
In addition, before we move to a complete reinstallation segment, its worth mentioning that certain game desktop clients, like Steam or Origin, offer the integrity checking tool.
With this tool, you can check for the integrity of the installation files and fix the possible corruption.
On the other hand, if thats taking you nowhere, the reinstallation should be your next step. Follow the instructions below to reinstall the affected program or game.
- In the Windows Search bar, type control and open Control Panel.
- Choose Uninstall a program.
- Right-click the troubling program or game and uninstall it. Before that, you might want to backup your saves.
- Now, navigate to the installation and AppData folders, and clear all remaining files.
- Start the setup and install the program again and look for changes.
Solution 3 Check GPU drivers
Finally, if both of the aforementioned solutions were futile, all our suspicion gets redirected to drivers.
The outdated or unsuitable GPU drivers can also provoke this or similar errors.
They are directly related to DirectX and the functionality of all related applications heavily depend on the GPU properly doing its job.
