Installation Methods

Direct Connection to the Internet

This method requires Sport Loader version 1.104 or higher. With this method, you connect your System 6 directly to a network connection to the Internet via its Ethernet port. The System 6 will update to the latest versions of the software that you have purchased.

USB Drive Method

WARNING: The System 6 update files must be the only files on the USB drive, and they must be installed sequentially, as described below. If the USB drive contains anything other than System 6 update files, these other files may be lost and you may damage your System 6.

  1. Make sure you have SportLoader v1.120 or greater. If not, install it by itself first. It must be the only file or item on the USB drive.
  2. Check to see if you have the compatibility libraries installed by looking for the label “(w/ lib updates”) in the “Linux Version” section of the SportLoader Diagnostics screen. If you do not have them installed, install them next, by themselves. The library files must be the only files or items on the USB drive. Click here to download the compatibility libraries.
  3. Download the appropriate updates from the page and place them in the top level (not in a subfolder) of a USB drive. The updates must be the only files or items on the USB drive. Install the updates.
