Affects Version/s: 2.21
Fix Version/s: None
You landed on this page because the game detected an error to start the game.
The problem occurred, because the game failed to retrieve the number of Vulkan extension properties.
The issue is known to occur if you manually removed the amd-vulkan64.json file from the Windows/System32 directory on a system with an AMD graphics card. If you did so and have a backup of that file, you are advised to restore the file, restart the machine and try to start the game again. Please note that it's possible that afterwards you are redirected to a different page with a different startup error. In that case, please follow the instructions on that page and don't remove the file again.
If you don't have a backup of that file at hand and/or the file has not been removed, please do a clean reinstallation of your graphics card drivers, reboot the machine, and try to start the game again.
If you still happen to run into this problem and a clean reinstallation of the graphics card drivers didn't solve the problem, please send a mail to email@example.com (Subject: "X4-271 - Exitcode 233") with a screenshot of the popup error you got and your dxdiag and vulkaninfo attached. This wiki entry explains how to create this information.
