# unable to launch LibGDX Particle Editor.jnlp

I am not able to launch LibGDX ParticleEditor.jnlp file on my system(win7 64 bit) with java7.

when I execute this file with javaws.exe in jre7/bin folder, it displays splash screen of badlogic games for jst 2-3 sec but after that it gives an alert having error message "Unable to launch application". And the exception is :

com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: http://libgdx.googlecode.com/svn/jws/gdx-tools.jar

I'm guessing you have 64 bit java installed. The ParticleEditor.jnlp fails to run on a 64 bit JRE. What you would want to do is:

1. Download a 32 bit version of JRE. Here is the Oracle link for that: http://www.oracle.com/technetwork/java/javase/downloads/java-se-jre-7-download-432155.html Just make sure you select a "x86" version of the JRE from the list, appropriate for the platform you want to launch the .jnlp file on. (Mac is not supported as far as I know. In case it already is, please correct me.)

2. Assuming you're on Windows, locate the "javaws.exe" file under "C:\Program Files (x86)\Java\jre7\bin" (of course, this is its location on my desktop, the location on yours should be similar). Notice the "C\:Program Files (x86)" folder - this is where all your x86 (32 bit) stuff goes - as opposed to "C:\Program Files", for 64 bit stuff.

3. Drag and drop your .jnlp file onto the javaws.exe file.
