Download G.Projector for Windows

G.Projector requires a computer with a Java 7 virtual machine, or better, installed.

Download G.Projector

The G.Projector for Windows download is a ZIP archives of approximately 7 MB. It is a "universal" version that should run on both 32- and 64-bit Windows.

If you are looking for additional overlay files compatible with G.Projector, any of the optional "outline overlays" available from the Panoply software website may be used.

Install and Run G.Projector

The G.Projector 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 G.Projector, it won't work.

The G.Projector archive contains a folder which holds the following items:

  • Double-clickable G.Projector.exe application.
  • Java application files in a folder called "jars".
  • Sample source map images in a folder called "sample_maps".
  • A README file.

The folder called "jars" must remain in the same location as the G.Projector.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, G.Projector will not work.

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

Debugging Installation Problems

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

If you find that after download and installation, G.Projector 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 G.Projector, 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 G.Projector 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.
