Nowadays, Internet Explorer is the only browser with support for Java plugins and applets (NPAPI). Many java issues are related either to the Java version installed on your PC or to the cache.

Anyway, JavaFX is not really an applet and doesn’t use a browser plugin to run. It is a set of graphics and media packages used by programmers to create and design Java applications.

Therefore, errors related to the JavaFX application may appear in your browser. Is this the issue that bothers you too?

Here’s how to fix the Internet Explorer error that says JavaFX application could not launch due to system configuration.

JavaFX does not run into your browser but runs from a browser. When you click the link, the app using JavaFX should be downloaded and then run on your desktop, like any other standalone Java application.

There are multiple web browsers available besides Internet Explorer. Windows 10 comes with Microsoft Edge but you can also download and install Opera, Chrome, Firefox, etc.

It is always a good idea to have more than one browser available. They should do the same thing, but there are Internet services that are supported only by a particular browser.

  1. Go to Control Panel.
  2. Adjust the view to Small Icons from the upper right side.
