Please try to restart the game launcher and download any damaged or missing game files again after forcibly terminating the game process in the Windows Task Manager.

If there was a network interruption, connection delay, or any other issue during the installation process, it's possible that the files have been corrupted.

In such cases, we recommend uninstalling the related program and performing a fresh installation.
* Please ensure that you have at least 5GB of available space on the hard disk where you want to install the game.

If you have already reinstalled the game but it still doesn't run, you may also try resolving the issue by installing the Visual C++ redistributable package.
