Install and Run Panoply

The Panoply package for Windows comes as a ZIP archive. You must manually extract this archive. Some versions of Windows allow you to run programs from a zipped archive without extraction, but if you try that with Panoply, it won't work.

The Panoply archive contains a folder called PanoplyJ which holds the following items:

  • Double-clickable Panoply.exe application.
  • Application code files in a folder called "jars".
  • A README file.

The folder called "jars" must remain in the same location as the Panoply.exe application. Also, all .jar files in the jars folder must remain there. If you move or remove that folder or any of its contents, Panoply will not work.

To run Panoply, just double-click on the Panoply.exe application.

Debugging Installation Problems

You must extract Panoply from the ZIP archive before you try to run it. If you simply open the ZIP file and then double-click on the Panoply icon, you will get a class-loader error because it cannot access some files.

If you find that after download and installation, Panoply for Windows won't start, a possible reason might be that you don't have a Java Runtime Engine (JRE) installed on your computer. To check for this, use the Sun utility that looks for Java on your desktop and automatically downloads it if necessary. Go to the Java.com website and click on the "Free Download" button.

Note: It is possible to have a Java plugin enabled in your web browser which allows you to run applets, but not have a JRE installed which allows you to run Java applications.

If when trying to start Panoply, you see an error msg stating "EXE4J_JAVA_HOME not found", the problem may be that there is a 32-bit vs. 64-bit mis-match between the Java you installed and the type of Panoply you downloaded. If you are on a 64-bit Windows machine but used a 32-bit version of your Web browser to install Java from the Java.com website, you may have ended up with a 32-bit JRE. See the Java.com FAQ for more information.

Color Tables and Map Overlays

Beginning with version 4, Panoply's "standard" selection of color tables and map overlays is built into the application. Additional color tables and map overlays may be opened for a single session or added to your favorites library for continued use. See the Panoply website for these optional support files.

For additional scale colorbar palettes, J.J. Green's cpt-city website includes many CPT format files that are compatible with Panoply.
