Happened to me too. Uninstall, reboot, make sure correct Java is installed, this is the tricky part. Jave JRE or JDK, this is not explained good enough and also on the Java website not great explanation, since they run from oracle and
java.com, plus many different third parties.
If you are still unable to get past this step, and you have not done so already, I would suggest opening a ticket.
Please provide as much detail as possible about the system specs you are using, the steps you have taken to remedy the problem, and what the problem is seems to be. Also please include a link to this thread for reference.
