X3DAudio1_7.dll is missing

You just started to play your game (possibly Metro 2033) and saw the error pop up about X3DAudio1_7.dll is missing.  This error is about Microsoft’s DirectX missing a few required files. All you need is a simple update, so let’s get straight to the fix.

Head over to Microsoft’s website to download DirectX End-User Runtime.  This file will update your DirectX, regardless of what version you have installed.  I had this issue on a Windows 7 machine and after the update was applied the error message was gone.  On previous versions of Windows, you may need to reboot.

God, shouldn’t have trusted the Dx 9.0c installed with the video card.  As much as I should have thought about that, I couldn’t have done it without this article.
Thank you for the help, keep on rockin’ ;D

“An internal system error occurred. Please reffer to DXError.log and DirectX.log in your Windows folder to determine the problem.”

That’s what I got when I tried installing it. Can you help me out here for a bit : ?
