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.

Once you have performed the steps above, close the Internet Options window and open your browser again.

If you had Favorite Bar active, you will have to activate it again by right-clicking below the address bar and selecting the Favorite Bar.

2. Use another browser

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.

3. Check Java Security settings

Go to Control Panel.

Adjust the view to Small Icons from the upper right side.

Click on Java.

Go to the Security tab.

Change your security level from High to Medium or from Very High to High, depending on your Java version.

Click on Edit Site List to add the website to the Exception Site List.

Use Add button and type the complete link to the website.

Click again on Add.

On the Security Warning windows, click on Continue.

You can close the Java Control Panel and lunch the website again. If a security warning pops up, make sure to click on Run.

4. Clear Java’s temporary files

Open Java Control Panel. Follow the steps 1-3 from the above solution.

From the General tab, click on Settings.

Click on Delete Files.

Click the OK button to close the Java Control Panel.

If you still continue to encounter the same issue, the last thing to do is to check the application requirements.
