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

Question

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 cert

Answer 1

I had a problem with Java 8u31 and IE10, it didn't see Java until I did 2 things:

• delete temp files (all kinds)
• reset all zones to default (Options -> Security -> ...)

Answer 2

Not exactly the same problem for me, because I was running the last java version 1.8.0_92, IE v11 and windows 7.

My situation was also that I had Chrome as the default browser.

So what for me fixed it, was to set IExplorer as the default browser again, uninstall Java, go to Java.com using the IExplorer, and from the IExplorer download and install Java again to the last version.

1. Go to Control panel.
2. Double click on Java.
3. Go to Security tab.
4. Change security from high to medium.

Your applets will run.

If they are still not running then you have to add that website name in exception site list of Security tab of Java in Control panel.

Answer 4

I know Mickey S. solved his issue with Java 8, but Pavel S. was on to something. If you're working locally with an applet, setting your Intranet Zone to Low security and then setting Java security in Control Panel -> Java -> Security setting to Medium from High does solve the problem of running local applets with Java 7u51 (and u55) on Win 7 with IE 11.

(Specifically, I have a little test tool for barcode generation from IDAutomation that is crafted as an applet which wouldn't work on the above config, until I performed the listed steps.)

Answer 5

Update deployJava.js.

Our site uses a local copy of deployJava.js; updating it to the latest copy has fixed this issue in IE11. (We will probably just start using the web version of deployJava.js instead of a local copy).

However, a (very) similar problem persists for our Safari users.

Answer 6

Finally resolved my java install issue on Win 7 64-bit running IE11.

Even though I installed the latest Java (65) via a java auto-update prompt, tried a verify java version and java failed to run, shut down all IE instances, failed to run verify again, shut down all running programs, failed to run verify again, rebooted, failed to run verify again, re-installed 65 again (shutting down the browser manually as it downloaded), and finally verify ran. What a pain.

The message I kept receiving was "The page you are viewing uses Java ..."; e.g. https://www.java.com/en/download/help/ie_tips.xml. I do use sleep mode on my desktop and I believe that this is probably the major issue with install and IE with its "clever" integration into the OS and explorer/desktop. I thought the government told them to not do that. I've had issues with CD-ROM drive disappearing and other unexplained periodic issues; all cured after a full reboot. They are infrequent, so I live with them for the convenience of faster startup times.

Hope this helps someone!
