I get this message when I install the G-Force visualization from Soundspectrum on Windows 8.1. It says that d3dx9_43.dll is missing and is incompatible with Windows 8.1. it was for Windows Media Player on Windows 8.1. The visualization was only for Windows XP/Vista/7.

The program can't start because d3dx9_43.dll is missing from your computer. Try reinstalling the program to fix this problem. 

Hi,

I made a test in our test enviroment, Windows 8.1 X64 Enterprise, no problem with it.

According to the error message, it should be directX problem, your system lost d3dx9_43.dll. please install the DirectX Runtime to solve your issue:
