The third-title in the hugely popular strategy game Crusader Kings is out and although the experience has been mostly positive with few hiccups, there have been complaints of the game crashing at startup, not launching, and missing d3dx9_41.dll and d3dx9_43.dll file.

The d3dx9 dll file is a part of the Microsoft DirectX and programs that rely on the Microsoft software will fail to launch and result in an error when there is problem with the DirectX files. Users can encounter the Crusader Kings 3 d3dx9_41.dll or d3dx9_43.dll missing error or any other. The error message can vary and is usually one of the below.

  • D3dx9_43.DLL Not Found

  • File d3dx9_43.dll not found
  • D3dx9_43.dll not found. Reinstalling might help fix this.

While the Crusader Kings 3 not launching can be caused due to initialization problems, lack of privileges to the game, corrupt game files, outdated graphics card drivers, outdated Windows, or a problem with the launcher.

Stick around and we will help you resolve both the errors in the game.

Fix Crusader Kings 3 Not Launching

If you have encountered the Crusader Kings 3 Not Launching problem, the first thing you must do is restart the system and attempt to play the game. It’s always best to suspend all other programs expect the Microsoft services before launching the game. You can do this from the MSCONFIG utility.

If the game still fails to launch, provide it with admin rights. Click on the desktop shortcut or the game executable and select Properties. Go to the Compatibility tab and check Run this program as an administrator.

The next fix you can try is checking the integrity of game files using the Steam function. If the game itself is corrupted that could also lead to CK3 not launching. Here are the steps to check and repair corrupt files on Steam.

  1. Launch the Steam client
  2. From the LIBRARY, right-click on Crusader Kings III and select Properties
  3. Go to LOCAL FILES and click on VERIFY INTEGRITY OF GAME FILES…   

If you have not updated the graphics card in a while, we suggest you do it before launching the game. New games are designed to run on the latest driver software and an outdated software can cause conflict and lead to the Crusader Kings 3 not starting or launching problem.

You must also do the same for the operating system. Ensure that your Windows is updated to the latest build.

If all else has failed to resolve the issue, you should try to reinstall the game as well as the launcher – the Steam client. This should effectively resolve the not launching or starting problem with CK3.
