Download d3dx9_42.dll
Sometimes users don’t know how to deal with errors and run to forums in a panic, looking for a solution to their problem. However, the problem is not always so complicated - and today we will prove it to you. First, let's look at the name d3dx9_42.dll. This is a library, the file extension indicates this. d3dx clearly clearly hints that the file belongs to DirectX resource, and definitely to one of the kits - Direct3D. The number 9 indicates the DirectX version. 42 is the number of the library.
We figured out the name: now these are no longer faceless letters, but a clearly defined problem - something with DirectX.
The solution to the problem is insanely simple. If DirectX has not been installed before, simply go to Microsoft.com - the official Microsoft website - and look for the "Downloads" section or "Download Center". When we get to this section, we immediately type “DirectX” into the search and download the top search result. We install reboot the computer - the error should not appear.
But someone will say - I already installed DirectX! Then the problem may be an incorrect installation - either DirectX or games. First, we’ll try to make do with little expense: download the DirectX installation file, delete the previous installation and install it again, reboot the computer. If the error still appears, you will have to reinstall the game. Most likely, if the installation now proceeds without incident, the error will be corrected. If the problem is not solved, then you need to download the file separately.
