The installation of Java JDK can easily be accomplished using the wizard. If in the course of the installation the path of directory has to be changed, a second intermediate step is necessary (please refer to the corresponding screenshot!). However, in such a case default settings could still be used.
Some applications require that environment variables be set correctly (please change accordingly the directory path of your Java JDK entry!):
To correctly set user variables: JAVA_HOME C:\Programs\Java\jdkVERSION
To expand systemic variables: Path <formerPath>;C:\Programs\Java\jdkVERSION\bin
