Solved: d3dx9_42.dll not found on OGRE Demo Example

OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D engine written in C++ designed to make it easier and more intuitive for developers to produce applications utilising hardware-accelerated 3D graphics. The class library abstracts all the details of using the underlying system libraries like Direct3D and OpenGL and provides an interface based on world objects and other intuitive classes.

I just try OGRE application demos which I get from this site. But, when I double click file application, the application wouldn't run and I get messages
"This application has failed to start because d3dx9_42.dll was not found. Re-installing the application may fix this problem" and this one "OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic lybrary .\RenderSystem_Direct3D9. System Error: The specified module could not be found. in BynLib::Load at ..\..\..\..\OgreMain\src\OgreBynLib.cpp(line 91)".

Then I search in internet, aldamdulillah I found the solution. Just download file that needed, and it's work normally. That's file can de downloaded on here.

After got that's file, just copy or cut and paste to Windows System32 folder. Then, try it the file application (SampleBrowser) again. As soon as, we'll get the result :-)
