Uninstall Java versions before installing

1. If the above instructions fail to resolve the issue, it is recommended that you uninstall all existing Java versions from the system.
2. Reboot the system after you uninstall all Java versions, before trying to install.

Option 2: Disable Java content through the Java Control Panel

This option disables Java content in the browser prior to installing.

Reinstall Java and re-enable Java content in the browser
