Install the latest version of Microsoft DirectX. Chances are, upgrading to the latest version of DirectX will fix the d3dx9_27.dll not found error. Microsoft often releases updates to DirectX without updating the version number or letter, so be sure to install the latest release even if your version is technically the same.

Assuming the latest DirectX version from Microsoft doesn't fix the d3dx9_27.dll error you're receiving, look for a copy of DirectX on your game or application CD or DVD. Usually, if a game or other program uses DirectX, the software developers will include an installable copy of it on the setup disc. In some cases, the DirectX version included on the disc will work better with the program than the latest version available online. Uninstall the game or software program and then reinstall it again. Something may have happened to the files in the program that work with the d3dx9_27.dll file, and a reinstallation could solve the problem. Restore the d3dx9_27.dll file from the latest DirectX package. If the steps above haven't worked to solve your issue, try extracting the d3dx9_27.dll file individually from the DirectX package. Update the drivers for your video card. While it's not the most common solution, in some situations, updating the drivers for the video card in your computer could correct this DirectX issue.
