This guide will walk you through InterPSS installation process. It also outlines key administration steps to maintain InterPSS user data.

Download InterPSS Release

First, please download InterPSS from SourceForge directly. InterPSS also has a development release, which has the latest features under development, but may not be fully tested yet and may contain bugs.



Install InterPSS on Windows

Please backup your existing InterPSS installation before proceeding to a new InterPSS installation.

Check Java installation

InterPSS is developed using Java programming language. InterPSS depends on Java runtime environment from SUN Micro System to run. To check your computer Java installation, launch a CMD window from Start/run/cmd and type the following command

  C:\>java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode)

Make sure that your Java version is "1.6.0" or above. If you do not have Java installed on your computer, please go to SUN Java Distribution Site to download Java JDK 6.0 and install it to your computer.

Unzip Installation File

InterPSS release distribution file is a zip file. Unzip the installation zip file to a temporary directory.

Double-click or run the install.bat file, distributed in the zip file, to install InterPSS. You may need to modify install.bat, if your Java installation is not in your Path.



You need to accept InterPSS open-source license to continue InterPSS installation.



  • Ipss/User Workspace: You have option not to install Ipss/User Workspace (Ipss Workspace + Ipss/User Database Files). If you already have an existing InterPSS installation, and have existing projects in the Ipss/User Workspace, we recommend do not install Ipss/User Workspace by un-check Ipss Workspace and Ipss/User Database Files. Otherwise, your existing files in the Ipss/User workspace directory and data in the User database will be overwritten by the new installation.
  • Sample Workspace: You have option not to install Sample Workspace (Sample Workspace + Sample Database Files). InterPSS Sample Workspace includes latest InterPSS samples. We recommend install with each new release.
