Started getting the error listed in the title on my developer box. Get if for both the designer and project launch. Still runs on other boxes. Here are the Exception details JNLPException[category: Security Error : Exception: null : LaunchDesc: PICS-AL Inductive Automation PICS system in Alagoinhas, Brasil ] at com.sun.javaws.security.JNLPSignedResourcesHelper.checkSignedResourcesHelper(Unknown Source) at com.sun.javaws.security.JNLPSignedResourcesHelper.checkSignedResources(Unknown Source) at com.sun.javaws.Launcher.prepareResources(Unknown Source) at com.sun.javaws.Launcher.prepareAllResources(Unknown Source) at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source) at com.sun.javaws.Launcher.prepareToLaunch(Unknown Source) at com.sun.javaws.Launcher.launch(Unknown Source) at com.sun.javaws.Main.launchApp(Unknown Source) at com.sun.javaws.Main.continueInSecureThread(Unknown Source) at com.sun.javaws.Main$1.run(Unknown Source) at java.lang.Thread.run(Unknown Source) ---

What version of Java do you have on that box? ---

7.5 But just noticed it does say it is 32bit. This is not the gateway, just a notebook running windows 7 ---

Switched it to 64bit, but same problem. ---

Its probably having the same problem because the ignition.conf file is looking for the 32 bit installation path still. You will need to modify this file for it to find the 64 bit java 7 jre. You can find the ignition.conf file in C:\Program Files\Inductive Automation\Ignition\data\ignition.conf. Once there, open this file in a text editor, notepad will work. Look for this line # Locate the java binary on the system PATH: wrapper.java.command=C:/Program Files(x86)/Java/jre7/bin/java.exe and change it to this # Locate the java binary on the system PATH: wrapper.java.command=C:/Program Files/Java/jre7/bin/java.exe ---

That brings up another issue, when this occurred the other day, I deleted the directory hoping to force it to download the files again. Apparently that is not happening. Can I force a new install… ---

What directory did you delete and what files did you hope it would reinstall? What are you wanting to force to install? Is this on a client machine or is it on the server? ---

This is a client machine that I develop on. I deleted the directory C:\Program Files\Inductive Automation Usually when I go to the designer mode from a new machine, it downloads I assume the contents of this directory… Essentially I need to rebuild it… ---

Ok, I would go into the control panel and then programs and features and uninstall all versions of Java. Once this is done, go to the Java website and download the latest version, or a version you feel comfortable with. Download the 64 bit version if your using 64 bit windows. Once installed, in the control panel, go to Java. In the Java control panel select settings at the bottom of the window, in the next window select delete files, then ok. Now try to launch. ---
