Install DirectX End-User Runtime if your application or game requires an earlier version of DirectX

Some applications and games require DirectX 9. However, your computer includes a more recent version of DirectX. If you install and then run an application or game that requires DirectX 9, you might receive an error message such as "The program can't start because d3dx9_35.dll is missing from your computer. Try reinstalling the program to fix this problem."

To resolve this issue, go to the following Microsoft website to install DirectX End-User Runtime:
