Fix 4: Update your graphics driver

This issue is likely to occur if you’re using the wrong graphics driver or it’s out of date. So, you should update your graphics driver to see if it fixes your issue. There are two ways you can do this:

Option 1 – Download and install the driver manually

The manufacturer of your graphics card keeps updating the driver. To get the latest correct driver, you need to go to the manufacturer website, find the driver corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually.

Once you’ve downloaded the correct driver for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.

Option 2 – Automatically update your graphics driver

If you don’t have the time, patience or computer skills to update the graphics driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct driver for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All). 

You can do it for free if you like, but it’s partly manual.
If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

Relaunch your game to test your issue after updating your graphics driver. If your game is still unplayable, read on and try the fix below.

Fix 5: Reinstall your game launcher

The Crusader Kings 2 launching error might occur if the game is not properly installed on your PC. In this case, reinstalling your game is very likely the solution for you. Here is how to do it:

1) Run Steam.

2) Click LIBRARY.

3) Right-click Crusader Kings II, then click Manage> Uninstall.

4) Click Uninstall.

5) On your keyboard, press the Windows logo key and E at the same time.

6) Double-click Documents>Paradox Interactive.

7) Delete the Crusader Kings II folder.

8) Download and reinstall the game from Steam.

9) Try launching Crusader Kings 2 again.

If Crusader Kings 2 still won’t respond when you launch it, move on to the next fix.

Fix 6: Check for Windows updates

Windows releases regular updates to fix bugs. It’s probable that a recent update is preventing Crusader Kings 2 from launching correctly, and a new update is needed to fix it. So, you should check if there are any updates available. Here is how to do it:

1) On your keyboard, press the Windows logo key. Then, type windows update and select Windows Update settings

2) Click Check for updates, and then wait for Windows to download and install the updates automatically.
