Fix For “The File d3dx9_XX.DLL Was Not Found” Game Error

The d3dx9_xx.dll series of files are used by games that run with the DirectX framework. DirectX is used to render graphics for all of the latest games and is an integral part of the Windows system. However, it’s often the case that the d3dx9 DLL files can become damaged or corrupted, causing errors.

D3dx9_xx.dll Errors

It’s typically the case that Windows will show a “d3dx9_xx.dll” error when you try and play or install a game. The most typical errors that are shown include:

The file d3dx9_25.dll was not found

The file d3dx9_27.dll was not found

The file d3dx9_30.dll was not found

These files are vital for playing games on your computer as they help DirectX to function. However, they are constantly being misplaced, damaged or corrupted, making them unreadable for your computer.

How To Fix D3dx9_XX.dll errors

Method 1 – Update DirectX

Updating DirectX is the most effective and reliable way to do this. In order to update this part of your system, you should firstdownload the DirectX updater from Microsoft’s website. This will open on your PC and proceed to either update or reinstall your version of DirectX. This will replace all the current dll files on your computer that relate to DirectX with new ones, allowing your computer to read the files that it needs again. After the install has completed, you should restart your PC and then use a registry cleaner to clean out the registry database of your PC (see Method 3).

Method 2 – Manually Update The File

If you’re still getting the error after a DirectX install, then you might want to manually update the d3dx9_xx.dll file on your system. To do this, you should follow the information below:

Method 3 – Clean The Registry

– Download This Registry Cleaner

The ‘registry’ is a large database inside Windows which keeps a large list of references for the DLL files on your system. This central database is where Windows keeps a list of the DLL file locations for your computer, and is where your system looks each time it wants to use a dll file such as d3dx9.dll. Unfortunately, it’s prone to becoming damaged and corrupted and is constantly being unable to read the files and references that it needs to open the files that it wants. This is a major problem that causes a lot of damage to many different parts of your system. Running a registry scan will remove all the damaged references inside the registry, allowing it to run as quickly and smoothly as possible. You can download our recommended registry cleaner below:
