Download and Installation Instructions

The following installation instructions are for users running either Windows 2000 or Windows XP. However, the EdSim51 Simulator, because it is Java^TM based, should run on any operating system that has the Java Runtime Environment installed. Installation therefore on Linux, for example, should be similar to the steps described below.

But it should be noted that the simulator has only been tested on Windows 98, 2000 and XP and on Redhat Linux 9.0 so problems may occur when installing and running on other operating systems.

Get Java

The EdSim51 Simulator was developed in Java (from Sun Microsystems, Inc - http://java.sun.com). To run the EdSim51 Simulator you must first install the J2RE (Java 2 Runtime Environment). Of course your computer may already have the J2RE installed. To find out if you have the J2RE, or to install it if you don't, click on the following button:

There are three steps to ensuring your computer has the latest Java installed:

On the page that opens when you click on the above GET IT NOW button, click on the Download Now! arrow.
Click on the Download button on the new page that opens. There are two options - online and offline. They both do the same thing but online tends to be faster. For more information, click on the Instructions link on that page.
When installation is complete, click on the Verify Installation button. This will test your computer to see if Java was successfully installed.

If you think Java is already on your computer, you can skip the installation step and test your computer for Java by clicking on the Verify Installation link.

EdSim51 Simulator Installation

The simulator is packaged in one file called edsim51.zip.

Click this button to download ->

The simulator is best viewed with screen resolution of 1024 * 768 pixels or greater.

version number:

1.19.4

Keep Up-to-Date with the Latest Version of the EdSim51 Simulator
Features are sometimes added to the simulator. You should return to this page periodically to see if a newer version is available. As newer versions are made available the version number beneath the install button will be updated.

To get the newer version simply follow the same download and install procedure (as described below) and replace the old edsim51.jar with the new.

You can save the zip file anywhere on your computer.

Unzip

You will need to unzip the edsim51.zip file. With newer versions of Windows you can simply double-click the zip file. Inside the zip file you will find one file called edsim51.jar - copy this file to another location on your computer's hard drive.

If your computer cannot automatically unzip the file you can download a zip/unzip package that will unzip it for you - see Google's listing. Or you can get the jar file on its own (see Just the JAR File below), but be advised that some browsers corrupt jar files when you attempt to download them.

Alternate Download - The JAR File

If you do not have a method of unzipping edsim51.zip you can get the jar file on its own.

-> edsim51.jar

You may need to right-click this link to save the target. Why? See below.

Also, when downloading the JAR file, make sure the file is saved with .jar extension. Some browsers automatically add a .zip extension to JAR files. The JAR file will not launch when double-clicked unless it is saved with the .jar extension.

Why might I need to right-click the JAR file to download it?

When you click on a JAR file (normal left-click) some browsers try to display the file rather than download and save it on your computer. To avoid this, you should right-click the link, then choose the option to save the file.

Launching the EdSim51 Simulator

On Windows, to start the simulator simply double-click on the edsim51.jar file, or you can start it from the command line.

Launching from the command line in Windows:

Go to Start->All Programs->Accessories->Command Prompt

A terminal like the one shown below will appear

Type cd %java_home% and hit Enter, as shown above.
Then type bin\java -jar c:\edsim51.jar and hit Enter.

In this example, the file edsim51.jar was saved in c:\ - you must make sure to type the full pathname to the folder in which you saved the jar file. For example, if you saved edsim51.jar in a folder on the c:\ drive called simulator, you would enter the following line:
bin\java -jar c:\simulator\edsim51.jar

Launching from the command line in Linux:

The process in Linux is similar. In a terminal, navigate to the folder in which you saved edsim51.jar then type
$JAVA_HOME/bin/java -jar edsim51.jar and hit Enter.

Operating System not Supported

As stated earlier, the EdSim51 Simulator was developed using Java and it may therefore run on any operating system that has installed the Java 2 Runtime Environment version 1.5 or later. However, some operating systems are not recommended by Sun. Therefore, when installing the J2RE you may be presented with the following dialog box:

Even if you are presented with this warning you may proceed with the J2RE and the EdSim51 Simulator installation. The simulator has been tested using Windows 98 First Edition without any problems being encountered. If you find the simulator does not work with your operating system please advise us here.
