    Hi @MDeb ,
    which vesrion of Java are you using? It seems like the one you use is not compatible.

    Best,

    @MDeb yes that is certainly your problem. RapidMiner must use JDK 8.x

    Hi,

    depending on your other requirements, it might make sense to set up java alternatives to easily switch between different Java versions:

    Hi. Java 8 is required specifically (not even newer versions). Had the same problem (on Ubuntu).
    Soln:
    1. sudo apt install openjdk-8-jdk openjdk-8-jre # to install required jdk.
    2. sudo update-alternatives --config java # to view your jdk versions and choose a comaptible one.
    3. select the version with the java8 (1081) in my case. # Use the number in the first column.
    4. cd to location of RM. # go to location of RM using terminal.
    5. ./RapidMiner-Studio.sh # this will start installation. Be patient.
