BTW I am on WIN XP SP3
OK, it seems that LOADUI needs to build some files on the first load, just switching back to JAVA6 will not work as there will be missing files that load UI builds on the first run. What I did was uninstalled JAVA7, LOADUI and JAVAFX then I restated and made sure my java version was the later by typing
java -version in cmd window. Should look something like this.
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)
I enabled the console output in java by going to control panel or type
javaws -viewer close the cashe window and you should see a tab on the java control panel called
Advanced click that. exspand the java console and tick the "SHOW CONSOLE" radio button.
This is rutamentry but its nice to see whats going on under the hood.
Install LOADUI just as you would if it was a new install, if you do not have Internet you will need to download JavaFX from another computer and install it on your machine.
When you run it you will see the console and should work. If not copy the log and post it.
I hope this works for you as it did for me.
