    I'm facing the same issue. Apparently Jdev 10 deprecated the use of -d64 and -d32 options. So the installer crashes while checking these options.

    I faced the same issue. My solution was to download the macOS version of JDK 1.8 from

    NOTE: The JDeveloper installer requires the actual JDK, not a JRE.

    After installing JDK 1.8, I modified my .profile as follows:


    JH=$(ls -1d /Library/Java/JavaVirtualMachines/jdk1.8*.jdk | tail -1)

    export JAVA_HOME="$JH/Contents/Home/bin"

    export PATH=$JAVA_HOME:$PATH


    In the case of multiple versions of the JDK 1.8 installed, the above method will take the latest installed version.

    NOTE: After editing .profile, quit and restart the in order for changes to take effect. Then cd to where you have the JDeveloper .jar files and continue with the installation as per the JDeveloper instructions.
