DataGrip doesn't run due to weird Java error

Hello,

I installed DataGrip on Windows 10 and set up a database connection. However, when I test it i get this weird error:

Error: Connection to MySQL - mein_rasenroboter@localhost failed: Exception in thread "main" java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at com.intellij.database.remote.RemoteJdbcServer.main(RemoteJdbcServer.java:15) .

I think I'm missing something on my system, like a java class that handles SQL stuff or so? I tried installing it, but still I got this error. I don't know if what I tried was necessary and if so, what I did was correct. I'm not sure what I'm doing here anymore, I'm so confused. There is no good explanation on this anywhere in the documentation. What do I have to do to make DataGrip run? I thought just installing the program itself would be enough to connect to a DB server? I'm at my wits end here, I just don't know enough about this stuff. Can someone help me?
