System Requirements

In order to run and use this calculator, your computer must:

1. Run the Windows operating system in any of the following versions:

  • Windows Vista 
  • Windows 7 
  • Windows 8
  • Windows 10

2. Have at least 11 megabytes of free disk space for the calculator software.
Your computer will also need additional disk space for the forms the calculator generates (roughly 200 kilobytes per calculation/case).

3. Have software installed for viewing PDF documents.
The forms have been tested and work properly in the free Adobe Acrobat Reader available for download at The forms have not been tested in any other PDF readers.

Installing the Calculator

Downloading and installing the calculator is a simple process requiring only a few clicks to complete.

STARTING THE INSTALLER: First, click the Download Calculator button above. Depending on which web browser you use and how you've set it up to handle download files, you may be prompted to 'Save', 'Run', or choose between saving and running the calculator. Either option will work. Choosing 'Save' will place a copy of the installation file on your computer, while 'Run' will not. If you choose 'Save', you may have to locate the installation file on your computer and double click it to begin the installation process.
SECURITY WARNINGS: At two points during the installation process, you will be presented with a Security Warning that says the publisher cannot be verified. The reason this security warning exists is because the calculator does not currently have a third party security certificate included.  The certificate itself does not alter the software; it merely tells your Windows PC that we, the publisher, have purchased a security certificate and registered with the third party. There is no malicious content included with the software, so you may choose to run/install the software without risk.
WHAT IS BEING INSTALLED: The calculator requires that Microsoft SQL Server (a database) is installed on your computer. The calculator installer will automatically handle this; all you have to do is accept the terms of the license agreement to download and install this component.

After Installation

The calculator will be available via a desktop icon or the programs list in your Start Menu. However, once installation is complete, the calculator will open automatically for the first time and present you with an options screen. It may take a minute or so for the calculator to run the first time. To learn more about setting options in the calculator, view the Getting Started Guide.
