No suitable Java runtime environment found on this system

Some customers that use the Microsoft Internet Explorer web browser have reported that they are no longer able to run BradLIVE. When attempting to run BradLIVE, the following message is received:

No suitable Java Runtime Environment

Reinstalling Java does not fix the problem.

We believe this may be caused by operating system level and/or Internet Explorer level updates that break BradLIVE launch functionality.

The workaround is to use one of the following web browsers instead of Internet Explorer:

  1. Chrome
  2. Firefox

  2. Find your Java control panel within your list of programs
  3. Open the Java control panel
  4. On the General tab, click "Settings"
  5. Click "Delete Files"

Red X appears

If there is a red X over where BradLIVE should appear and you are using IE8, then there are some configuration settings in Internet Explorer that prevent BradLIVE from downloading into your browser. You should install and try using either Firefox or Google Chrome.


Network Connection

Sometimes you will download the client, but it will be unable to connect back to the server. Please ask your IT department if a firewall is blocking your access to port 8079 on

Prompted for answernet login twice

Once the applet is downloaded, it asks for authentication to open a connection back to us. We are working on a fix for this, but for now, checking save password will save it temporarily.

If you see a red X above, then most likely Java is installed but it is configured to block part of the applet download. This seems to happen most frequently on IE8, but not on all IE8 systems.

Chrome doesn't have Java Plugin Installed

Starting with Chrome 42, Java is disabled by default for Chrome. Follow the instructions on Enabling NPAPI in Chrome Version 42 and later to re-enable the plugin.


Javascript is a simple scripting language used by default in all major browsers. Some security policies disable it for unknown websites. Lets make sure javascript is also enabled for answernet.
