"The program can't start because d3dx9_42.dll is missing from your computer. Try reinstalling the program to fix this problem."

When I try to load up almost any game, I get the error message "The program can't start because d3dx9_42.dll is missing from your computer. Try reinstalling the program to fix this problem."

 

The file is a crucial DirectX file, and it should be in System32, but it's not. I'm on windows 10, newest update. I've tried reinstalling the program, updating windows,to no avail. Any help appreciated, but I will say that you can't just update DirectX run time in windows 10, and you can't just install the .dll file from the internet.

 

Thanks!

I'm not sure if it is exactly the same file, but I've had problems running games on a new but fully patched Win10 laptop until I downloaded and installed directx from MS. Insane, but that is the way it is.

If that's referring to DX9, that isn't integrated with Win10. You need to download and install DX9c separately.
