Start Trace Modeler

Trace Modeler is a java application with very modest system requirements.

Requirements

If there's an appropriate java runtime environment (JRE) for your platform, you can run Trace Modeler. It requires a JRE for Java 2 SE 5.0 (a.k.a. 1.5.0) or better.

Chances are that you already have a sufficient version of the JRE installed on your system. If you want to check this yourself, run the following command from the command line

java -version

That should print the current JRE version on the console.

If you get an error message about an unknown command or unknown program, you do not have a JRE on your system. You can download it at http://www.java.com/en/download/manual.jsp.

Start Trace Modeler

How you start Trace Modeler depends on your platform:

Each will accept an optional filename that will be opened when Trace Modeler has started. This is especially useful if you want to associate .trace files with Trace Modeler.

Note that JRE's are notoriously slooooow to start the first time, so it could take up to 20 seconds before you see the main window come up.

A couple of things can prevent Trace Modeler from starting, depending on your platform

Should you try to run Trace Modeler on a lesser known platform or on a device that is not a regular desktop pc, please let me know as I'm always curious how Trace Modeler is used in the wild :o)

Note that you can tweak the startup process to increase the amount of memory available to Trace Modeler.
