JNLP Launch Error

I have a JNLP file that was working fine and it looks like my computer no longer runs it after I upgraded to Java 1.7 (32 bit jdk1.7.0_02) When I select view details in the Unable to launch the application dialog, the launch file appears as random characters and the exception is:

MissingFieldException[ The following required field is missing from the launch file: <jnlp>] at com.sun.javaws.jnl.XMLFormat.parse(Unknown Source)

You can see the file here: Download Trial Version of The Proctinator

It looks like the file is working on other computers running Java 6. Yet the computer I'm having issues with is able to launch other JNLP files just fine.

Any thoughts?

You might want to validate the launch file using JaNeLA before wondering too much about differences between versions. If the JNLP is invalid, it is anybody's guess as to how a JWS client will interpret it.

JaNeLA Report - version 11.05.17


Report for http://proctinator.com/dist/launch.jnlp

cvc-complex-type.2.4.a: Invalid content was found starting with element 'security'. One of '{resources, application-desc, applet-desc, component-desc, installer-desc}' is expected.

BTW - something in the description that will not be detected by JaNeLA.
