League of Legends if one of the best and absolutely free MOBA (Multiplayer Online Battle Arena) game. It combines the features of strategy and RPG games. The game is being developed by Riot Games Company. The game features a very simple and intuitive interface, good graphics and so many interesting characters that you can play. Also, the game doesn’t require a powerful computer to be played. However, yesterday I updated my graphic card drivers and after that when I run League of Legends Launcher and hit “Play LoL” the error message appears saying “The Program can’t start because d3dx9_39.dll is missing from your computer. Try reinstalling the program to fix this problem”.
The first thing I tried is to reinstall the game. I wasted few hours downloading and installing this game again. And guess what? It didn’t help me at all. As soon as I hit the “Play LoL” the d3dx9_39.dll is missing error appears. I was out of options, but my friend helped me and I couldn’t believe that the solution is that easy.
This solution can fix d3dx9_39.dll is missing in League of Legends for Windows Vista, 7, 8, 10. This error is caused by missing or corrupted .dll file that is supposed to be installed together with DirectX 9.
So, just download and install the missing d3dx9_39.dll file from here: http://fix4dll.com/d3dx9_39_dll
The instruction about how to install the .dll file will be provided on the downloading page.
Now you can enjoy playing League of Legends with your friends!
