    Use the correct version of Java that matches the software that you are trying to run. You will not be able to run programs that require Java if the version of Java that you have installed on your computer is incompatible with the program that you wish to open. You can try to change the settings on other programs to make them compatible with Java or upgrade or downgrade your Java version.
  4. How to Fix Java Picture 8
    Consider reinstalling your operating system if other attempts to repair Java fail. You will have to format your hard drive, which will consequently delete all previous data stored on your computer including Java. You should then be able to install Java correctly from scratch after the operating system has been reinstalled.
