If you find yourself with more than one EnergyGauge USA Icon on your desktop this table below may help you figure out which one it is you need to use. Keep in mind that in 2016 and in 2018 EnergyGauge launched new licensing systems so new purchases will only work with the newest version of the software. Any version earlier will not activate with the latest license process and will not be able to open.
