"Unable to load resource" when attempting to install using WebStart

Hi,

I have successfully launched an application using WebStart on the web server hosting the JNLP file.  However when I test it out on a users machine I get the following error messages in WebStart.  Any ideas?

Cheers,
Steve



An error occurred while launching/running the application.
