This is a very important update if you are using Windows XP to play latest PC games. Microsoft have released the latest DirectX 9.0c runtime libraries, updated in March 2009. It’s been quite a while since a new update for DX9 was released as the last one was released way back in November, 2008. Installing DirectX 9.0c March 2009 will ensure that you will have maximum compatibility with latest PC games, optimal performance and added reliability.

Although many people are unaware, the all too common missing dll errors when trying to launch new games (ex- missing d3dx9d.dll , d3dx9_25.dll, missing d3dx9_27.dll, etc) are mostly caused by an outdated DirectX version. Installing the latest DX runtime update should easily rectify such problems as well.


You can download the redistributable installer directly from Microsoft. There are two versions of the installer available – the web setup which will download necessary files over the internet and the SDK which includes a full standalone isetup and more.

    NIKKI: This post has absolutely NOTHING to do with the 9.0c SDK, downloading the SDK, or anything else you can dream up about the SDK. Consider this your reply. Try a forum/group/newsgroup that's actually related to the 9.0c SDK. (Hopefully you have already, since it's been about 5 months)

    As for me - just annoyed by MS's apparent constant RE-RELEASE of "9.0c" W.T.F.?? Couldn't they friggin call it 9.0c1, 9.0c2, or 9.0d, or SOMETHING? How completely forked is releasing updates of *anything* and keeping the exact same version number? (I know, it's called 9.0c March 2009, but that's still 9.0c!)
