Download and Installation

After clicking the link above, your browser will prompt you to either run the installer directly, or save it first to a local drive on your PC. If you save the file, you can run it later by double-clicking the file.

As the file is an executable file (.exe), your operating system may initially prevent the file from running, or give a warning about potential damage. This is a normal precaution to prevent unwanted software being installed on your PC. The file is digitally signed by PreFEED Corporation to confirm that the file is genuine. You can view the digital signing certificate by saving the file, then right-clicking on the file and viewing the file properties.

When the installer is run, you will see the InstallShield Wizard which will take you through the installation process.

Getting Started

There are many resources available to help you get started using EQUATRAN. Selecting File/Open from the menu initially brings up a list of example files, further information on which can be found in Appendix B of the User’s Guide. A series of tutorials is also available.


When you run EQUATRAN for the first time after installation, it will be in trial or evaluation mode. You can use the software in this mode for 30 days, after which it is necessary to purchase a licence to continue using it.

If you have purchased a licence, the software can be activated by entering the code which was sent to you following your purchase. A licence information dialogue is shown when the software is started. Click the Activation button and follow the steps in the wizard to complete activation. EQUATRAN needs to connect to our web server to complete the activation, so if you are using firewall software you may need to allow EQUATRAN to connect to the internet at this time. If your PC is not connected to the internet, or you are behind a corporate firewall that does not allow you to authorise the connection, please contact us by email and we will send you instructions for completing the activation process off-line.
