Software Download

If you don’t have the software installed, or you have a version older than 3.5, or you want to reinstall on a new PC, download the Installer.

If you already have version 3.5 installed on your PC and want to use the latest update, download the Updater.

The system works on Windows 7, Windows 8.1, Windows 10, and Windows 11. It is not compatible with Windows XP.

This software is compatible with all electronic models. Some models require a firmware update. If you want to know if your PC or electronics are compatible, download our diagnostic tool.

The driver for the USB port of Gyra/Forza models is already included in the installer and you don’t need to download anything else. In case the driver doesn’t install correctly, you can download the driver for Windows 7/8.1 or the driver for Windows 10/11.

USB models prior to 2018 require this additional driver when used with Windows 7. These models are not compatible with Windows 8/10/11, but it’s possible to update the hardware. Contact us.

For 2014 models and older that have a serial port connection, you may need to install the USB to Serial adapter driver that you purchased. Check the adapter manufacturer’s website.
