Can not run Java Applets in Internet Explorer 11 using JRE 7u51

c# java internet-explorer applet jnlp

Today I updated my Java version to 7u51. After the installation, I cleared Java Cache, browser's Cache, and logged into a secure website that uses an Applet to provide certain additional services to the user.

The applet is not working anymore. I accessed http://www.java.com to check the Java version detected in Internet Explorer, and the java website says:

We are unable to verify if Java is currently installed and enabled in your browser.

Internet Explorer 11 and JRE 7u51 can not verify Java version

Other browsers can check Java, and the mentioned applet works as expected:

Google Chrome and Firefox can verify Java after the update to 7u51

As the applet works as expected in other browsers, I can assume the problem is not the Applet nor its deployment files/processes, but the compatibility of JRE 7u51 with IE 11. I would like to know if there is any workaround for this.

As additional measure, I used the java.com tool to uninstall any previous and unsecure JRE version (using Google Chrome). After double checking IE 11, I can see the Java Addons enabled and versioned to 7u51:

IE 11 Java addons are enabled and up to date

I know IE has been improved; even so, we recommend to our customers to use Google Chrome or Firefox as these browsers have proven to be more compatible with our web applications. Unfortunatelly, we can not force our customers to use certain browser due to the common organizational restrictions about programs usage, etc.

Thanks in advance for any help.

Update (01/20/2014):

The following screenshot shows Internet Explorer 11 with Compatibility View configured for "java.com". It doesn't fix the problem in this case.

IE11 with Compatibility View doesn't fix the problem

We had the same problems with IE11 and new Java. Try to add your site to compatibility view. You can find here how to do it.

You can try now if it works or not. After that you can remove site from compatibility view and it should also run.
