Minimum requirements

Datastream Pro requires a pre-installed copy of the Java Runtime Environment (JRE). version 1.4.0 or later in order to run. You can download a copy of the Java runtime environment from The JRE must be on your system path, so that the "java" command can be run from anywhere. You can test to see if this is the case by executing the command

			 java -version
from the command line. If you get a response similar to this:
			  java version "1.4.2"
			  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
			  Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)
then you can safely run Datastream Pro.

  • Download this file to your system, extract it to the installation location.
  • Ensure that the Java Runtime Environment is available on the users path. (Must be 1.4 or later)
  • If nesseccary perform a "chmod" operation on to make it executable.

  • You will find some icons in the "icons" directory if you want to make a desktop or menu link to Datastream Pro.

  • If you haven't uninstalled the previous version of Datastream Pro which you had on your system, please do using the Datastream Pro uninstaller before installing the new version.

    • The version of Datastream Pro you had installed was earlier than Prior to this version the installer was not deleting all of the files in the installation directory. This bug was fixed in version
