Hi,
I try to install Aris Express with the executable on a windows 7 system with java 7 installed, but all I get is a notification that Java-Runtime-Version 1.6.0_10 or above not found.
So I installed the latest version of Java 6 as well, getting the same error afterwards.
I had more luck installing with the JNLP file AFTER I disabled the code verification of Java 7 (advanced option -> security at the java controll panel).
Just to let you know :)
