Troubleshooting Java: for Windows Users

Last Updated: May 25, 2017 11:02AM BST

As browsers move away from allowing Java based NPAPI applets, your choice is becoming more limited to utilise this tool (which is why our longer term plan is to remove it). On Windows, Firefox removed the ability in their standard version but have extended Java support in Firefox Extended Support Release (Firefox ESR). You can download this from the Firefox pages, see here

The applet is still supported in IE 10 or 9. Chrome, IE11 and Edge do not support Java applets (we mention a IE11 work around later in this article). 

In order to use the Java upload tool, users must have the latest version of Java installed on their machine and enabled in the browser. To verify the version of Java you are currently running, and to download the latest version, please head over to

The browser-specific instructions detailed below are given on the assumption that the user has installed the latest version of Java on the machine used to conduct the upload and it is not working.


Enabling Java in Firefox ESR

You will need Firefox's ESR version of the browser to be able to run Java applets, see the details above. Once you have the ESR of Firefox running, use the link.

If Firefox is still not seeing Java, go to the top of the browser, to the far right, select the Firefox menu button (or ALT+T+A in Windows XP), then Add-ons

The Add-ons Manager tab will open.

In the Add-ons Manager tab, select Plugins

Click Java (TM) Platform plugin to select it

Select Always Activate from the drop-down menu.

For further troubleshooting around Java, please visit here.

If you are unable to install Java, you should try our Desktop Application, which has Java pre-built into the software, find out more here.


Enabling Java for Internet Explorer versions 9, 10, (Microsoft have removed support for Java in IE 11 and Edge, see further down this page for a work around).

Click Tools and then Internet Options

Select the Security tab, and select the Custom Level button

Scroll down to Scripting of Java applets

Make sure the Enable button is checked

Click OK to save your preference

IE 11 & Edge work around for upload only

Uploading via the web HTML5 uploader and the desktop application works as normal but if you do want to use the Java applet for upload, IE 11 & Edge do not allow you as normal. There is a work around where you can emulate IE10 within IE 11 or Edge. This method works for upload only and assumes you have the latest version of Java installed.

Within Aframe, select the big green upload media button and your upload window will come up. You should now be greeted with the below screen shot - 

At this point you need to press F12, which will open an extra set of options, as shown below

Select the drop down window and a list of previous IE versions will show and by selecting them IE11 will emulate that browser, so select IE10.

It will automatically switch to IE10 and your upload window should now be working

Once you have finished uploading, just select the drop down window and switch back to Edge, then press F12 to remove the extra options.

If you need any help with this please please contact us via the chat or contacts and we will walk you through it.

Google Chrome

Google Chrome no longer support NPAPI Plugins, which is required for Java applets. Please utilise an alternative browser or Aframes desktop application
