d3dx9_39.dll for League of Legends

d3dx9_39.dll is the Microsoft DirectX dynamic link library executable file. The software is necessary for the launch and correct operation of various games, for example, League of Legends.

What is this file?

The Microsoft operating system is designed in such a way that various software require additional libraries to function properly. One of them is DirectX. The package is responsible for the correct rendering of 3D graphics. Accordingly, if the file is out of date or missing, an error will occur when you try to open the game. The problem is solved by manual reinstallation.

How to Install

Using a specific example, we will analyze the correct installation, as well as further registration of the DLL:

1. Using the button below, we download the archive with the component we need, then unpack the data along one of the system paths. We confirm access to administrator rights using the “Continue” button.

For Windows 32 Bit: C:\Windows\System32

For Windows 64 Bit: C:\Windows\SysWOW64

2. Open the Windows search tool, find the command line, right-click and select run with administrator privileges from the context menu. Go to the folder where you placed the DLL (operator cd), after which we register using regsvr32 d3dx9_39.dll.

3. We restart the computer and try to launch the game that previously generated the error.

Checking the bitness of a Microsoft operating system is very simple. To do this, there is a hotkey combination “Win” + “Pause”.

Download

The theoretical part has been completed, which means you can proceed to practice by first downloading the missing component.
