Hello,
In order for us to provide support, we do ask that you please write in English.
I understand that you are experiencing an error after you click the “Launch” button. Can you please let us know what version of the Launcher you are using? (this is located in the bottom-left corner of the Launcher).
Can you please post a screenshot of the error message you receive?
Can you please upload a .txt file of your Dxdiag so we can see your computer specs?
Thank you
