How to Fix D3dx9_37.dll Errors
Follow these steps in the order they're given below to try the simpler solutions first.
Do not, under any circumstances, download d3dx9_37.dll individually from any DLL download site. There are several reasons why download DLLs like that is never a good idea. If you’ve already done so, remove it from wherever you put it and continue with the following steps.
Restart your computer if you haven’t yet done so. The d3dx9_37.dll error might be a one-time issue and a simple restart could clear it up completely.
Install the latest version of Microsoft DirectX. Upgrading to the latest version will often fix a d3dx9_37.dll not found error.
Microsoft often releases updates to DirectX without updating the version number or letter, so make 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_37.dll error you're receiving, look for a DirectX installation program on your game or application CD or DVD. Usually, if a game or another program utilizes DirectX, the software developers will include a copy of it on the installation disc.
Sometimes, though not often, the version included on the disc is a better fit for the program than the latest version available online.
Uninstall the game or software program and then reinstall it again. Something might have happened to the files in the program that interact with d3dx9_37.dll and a reinstall could take care of the problem.
Restore the d3dx9_37.dll file from the latest DirectX package. If the above steps haven’t worked to solve your error, try extracting the d3dx9_37.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.
