The utility is written in Excel VBA so if you wish to use it you will need to have Excel 2000 or later installed on your computer (but you don't need to have any knowledge of Excel).
I recommend that you create a shortcut. Right-click on the utility in Windows Explorer and, while holding down the mouse button, drag it onto your desktop; then select "Create Shortcut" from the dialog box that pops up when you release the button. You will then be able to both launch Excel and load the file with just a double-click.
