Iceclient is recommended to be launched through Web Start, as this keeps it automatically up to date.

If you encounter problems with this method, check that :-

• You have an up-to-date Java runtime installed. You can download the latest from here.
• Try removing the 'cached' application. This will force web start to download everything again. To do so, locate the Java control panel (there is a link in Windows control panel, or use the 'jcontrol' command on other operating systems). In there, locate Temporary Internet Files, then the View button. From the window that pops up, you can remove installed Web Start applications.
