Hi, I think i made any stupid mistake and just don't realize it...
I use an AMD Ryzen 1700 @3GHz standard frequency. It sits on an Asus Crosshair 6 Hero and hast 32GB Ram. Its runs Windows 10 Home, 64bit, Version 1809, Build 17763.805
I did not install any Anti Virus programs but the Windows internal Anti virus (Windows Defender) and Firewall are activated.
The output of the installer is way to long, to copy paste it here and unfortunately I am new user and can not upload the .zip.
I just deleted WAMP and re installed it. Then I downloaded the one-file-installer (index.php) for shopware 5 from the shopware hompage and copyed it in the WAMP directory: apache2/htcdocs. Then i opened it in the browser and the setup startet installing shopware. Then i came to the point of setting up the mysql database again. The user name was set already (root). I put in the password, I chose during the installation and chose a database name, this error occurs then:

Do I first have to create a database manually and if so, where? Or is there already a database and I have to copy it's name in?
By the way: I chose that database name, because its identical to the that database name of my online shopware installation. Just in case, to avoid any future problems, because i am a beginner..
