Warhammer 40,000: Dawn of War is quite old game but still it’s one of the best in its genre. So, I’ve decided to install it on my Windows 10 64 bit operating system computer. I was expecting that some error will appear since the game was developed like 10 years before the Windows 10. To install the game I had to run the installer as administrator. After the installation was completed I tried to start the game and immediately got system error saying that d3dx9_39.dll is missing. Oh well, it’s not hard to fix this error.
D3dx9_39.dll is missing error is closely related with DirectX 9. Since Windows 10 doesn’t have DirectX 9 preinstalled you will need to install it by yourself, but I am not sure if it will let me to install the older version of DirectX over the new one, so I found the trick how to fix d3dx9_39.dll is missing error without installing DirectX 9. You just need to download d3dx9_39.dll library from here: http://fix4dll.com/d3dx9_39_dll. Now, simply place it into the game folder.
