  1. Did I help you? Consider a one time contribution to support new daily content on this channel. https://www.paypal.me/MDTechVideos

  2. I have to second the comment about moving the 32bit to the sysWOW64 folder AND the 64bit to the system32 folder. Only moving the 64 bit did nothing each time I tried until I downloaded both 64bit and 32bit to my laptop.

  3. i have a 64 bit computer and i downloaded the 64 bit, but the game im trying to play still says it's missing, can anyone help?

  4. If you are having this problem with games best thing to do is to install/reinstall/update DirectX, this worked for me

  5. I can only speak for myself but installing DirectX 9c fixed this for me, even though I already had DirectX 11 installed. Maybe it was an older dll that is not in the newer version.

  6. Microsoft has a fix for this also: https://support.microsoft.com/en-us/help/910813/game-error-the-file-d3dx9-xx-dll-was-not-found This should fix all missing files.

  7. it doesnt work cuz you have to install both files
    the 32 bit move it to SystemWOW
    the 64 bit move it to system32

    i did that and it worked

  8. HI MDTechVideos! I did every step that you did on the video, for the 64-bit version of Windows 10, restarted the laptop and reinstalled the game. However, I still can't launch the game that I want to play in my laptop. Please help, thanks! (Note: I'm still having this error message: The code execution cannot be processed because d3dx9_43.dll was not found. Reinstalling the program may fix this problem.)

  9. i did everything that you did…downloaded the file and dropped it into the 32 file… then i treid to start the game that i wanted to play but i got the same error message that the file was missing it makes no sense…..its like i never dropped it in ….my comp is 64bit so i download the 64 file d3dx9_43.dll
