D3dx9_30.dll is missing when installing video games

Yesterday, while trying to install the pretty cool PES 2011 demo on my new Windows 7 PC, i came across the following error message box:

Luckily i quickly remembered this error from previous installations and realized that i haven't loaded DIrectX on my new PC. If you haven't heard about DirectX, it can be defined as the technology that enables running video games in a Microsoft base computer or device. Long story short, i headed to the DirectX 9.0 installation page, downloaded and installed the latest version of DirectX which allowed me to get rid of the D3dx9_30.dll error.

Just wanted to share that with you guys. Enjoy Pro Evolution soccer!
