Update your version of the Java platform so that you always have the latest Java Runtime Environment (JRE). View and delete temporary files used by the Java Plug-in, which runs applets and JavaFX applications that are embedded in a browser, and by Java Web Start, which enables you to run Java and JavaFX applications over the network. The Java Control Panel provides the following capabilities: To start the Java Control Panel from the command line, enter \bin\javacpl.exe on Windows, or /bin/jcontrol on macOS or Linux. In JDK 9, the Java Control Panel was rewritten as a JavaFX application and the location of some functions has changed. Alternatives for applets and embedded JavaFX applications include Java Web Start and self-contained applications. Any environment variables (e.g.Note: Although available and supported in JDK 9, the Applet API and the Java Plug-in are marked as deprecated in preparation for removal in a future release.If not, it's better to delete them manually (since you will be re-installing them anyway, this should be fine). The Java directories (in either C:\Program Files (x86)\Java or C:\Program Files\Java) are actually deleted by the uninstaller.If you are installing just the JRE then the custom path could be something like C:\Program Files\Java\JRE (instead of the default C:\Program Files\Java\jre8). I am not sure if this is the cause however but so as to remove that possibility, when I re-installed Java I created a custom directory C:\Program Files\Java\JDK ( this was the 64-bit version a 32-bit version should have been placed in C:\Program Files (x86)) and directed the installer to put everything in that directory (instead of its default which would have been something like: C:\Program Files\Java\jdk_1.8.0.66). So a change in version number => changes the installation directory => may have an effect on some paths were system expects to find Java. I am saying this because Java by default tends to install itself into directories where the directory name has the version number. It's possible that this issue has something to do with what happens when Java update loads a new version to your system. The only solution that I have come up with in a similar situation: to uninstall & re-install Java. ![]()
