Matthias this was exactly what I needed! If you run the service manager and point it to the correct version of jvm.dll you don't need to worry about if your JAVA_HOME is correct. Since I was using 6.0.0.0 I needed to use Java 8 when Java 17 was already installed and set as JAVA_HOME. I opened this up, pointed to the java 8 JDK jvm.dll and it started right up afterwards.
