How can I fix the error d3d9.dll

Hi Antony,

1. when exactly did you D3D9. DLL error?

2 have had any changes made to the computer before the show?

3. what version of Windows is installed on your computer?

D3d9.dll problems result in one way or another by a problem with Microsoft DirectX.

The file d3d9.dll and d3d10_1.dll is one of many files in the DirectX software collection. Because DirectX is used by most Windows-based games and graphics programs advancements, d3d9.dll errors usually only appear when you use these programs.

Important note: Do not download the file d3d9.dll individually any "DLL download site."

Note: If you have already downloaded the d3d9.dll in these places to download DLL, remove it from everywhere where put you it and continue with the following steps.

Step 1:

Restart your computer if you have not yet.

D3d9.dll error may be a stroke of luck and a simple restart could clear up completely.

Note: the latest version of DirectX should be installed no matter if you are on Windows 7, Windows Vista or Windows XP. Installation can include DirectX9 and DirectX10 files but they run side-by-side without problem on all these operating systems.

Step 2:

Install the update from the link below and check if the problem is resolved.

End-user Runtime Web install DirectX

Step 3:

I recommend you perform the clean boot.
 
Put your boot system helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.
 
See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

Note: after a repair, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

Step 4:

System File Checker Scan SFC/scannow is a very useful command that you can use in any version of Windows. When the SFC (System File Checker) command is used with the/scannow switch, the tool analyzes all the important files of Windows on your computer and replace if necessary.

Missing and the corruption of the operating system (like many DLLs) files are probably the main cause of the major problems of Windows. In view of this, plus the fact that the SFC/scannow is completely automatic and very easy to use, the tool should be usually one of your top not troubleshooting.
