Invalid or Corrupt Jar FileA Windows user reported this error window:
One possible work around is to download the

java command on the
java -jar ptII8_0_1_setup_windows_64.exeIt looks like this error message is caused by a problem with the the .exe file that is produced by Launch4J. See http://stackoverflow.com/questions/5913120/java-embedding-jar-inside-exe for details.

1. Install Java, if necessaryTo run the Windows Ptolemy II installer requires that Java be installed on your machine.
If Java is not installed when you run the Windows Ptolemy II installer, then you will be directed to install a Java Runtime Environment (JRE). This JRE is separate from the JRE that is included in the Windows Ptolemy II installer.
Under Windows, the Ptolemy II installer includes a private copy of the Java Runtime Environment (JRE). The private copy of the JRE includes Java packages that are used by various domains and actors.
JRE vs. JDK
To run Ptolemy II, the Java runtime environment (JRE) is sufficient.
To run the applets in a browser, the Java plug-in is required. The JRE is bundled with the plug-in, so downloading the plug-in also installs the JRE.
To extend Ptolemy II with your own Java code, the Java development kit (JDK) or an equivalent Java development environment is required. The JDK includes a Java compiler.
Which Version of Java?Ptolemy II requires Java 1.5 or later, Java 1.5.0_22 is preferred, Java 1.6 will also work.
One way to determine what version of Java (if any) is installed is to run our Java Version Applet , which uses the Java 1.5 plug-in. Another way is to run the command below to see whether you have Java installed, and whether it is the proper version:
java -versionIf the command cannot be found, or the version that is printed is less than 1.5, you should install the plug-in, JRE 1.5, or JDK 1.5 or use download the installer that includes a private copy of the JRE.
Java Installers2. Install Ptolemy II
Where to install?Note that under Java 1.5.0, viewing local applets that have spaces in the path name may fail if the applet tries to download a data file. The workaround is to place the Ptolemy II installation in a directory that does not have space in the pathname. For details, see the Troubleshooting Guide.
In addition, the Copernicus code generator has a hard time with spaces in the path name because of limitations in parameter passing in Soot, a package that Copernicus uses.
