| SpringCharts is written in Java and therefore requires the Java Runtime Environment (JRE) to run on any platform. The JRE is included on Macintosh OS X and many Linux Platforms. Depending on which version of Windows is running on your machine, it may already come with the JRE installed. |
| To check your version of Java, follow these three simple steps: |
1. Open a Terminal.
Windows: Open a Command Prompt (sometimes called MS-DOS Prompt). You can find this program by clicking on the Start menu on the lower left side of your screen. Select Programs/Accessories/Command Prompt (or MS-DOS Prompt). |
| Macintosh: Open a Terminal. You will find this program in your Application folder inside the Utilities folder. |
| Linux: Open a Terminal Emulation Program window. |
2. Type the following:
java . -version |
3. Press the Enter key.
Your computer will tell you which version of Java is currently installed. Below is the output from a typical Windows computer: |

| Note: this screen is white on Macintosh computers. |
| If you do not have the JRE 1.4.2 on your system, you should download and install JRE 1.4.2 now. |
| To install Java Runtime Environment (JRE) 1.4.2 on your systems, select the JRE for your operating system from this list: |
| JRE 1.4.2_03 for Windows |
| JRE 1.4.2_03 for Linux (This file is packaged for download directly to a Linux system.) |
| Note: If you have problems during the JRE installation or if errors occur, please review the Installation Notes below. |
