If you had bothered to really look you'd have found a line that said -
"DOWNLOAD CE FOR THUNDER AC6" - when you move you cursor over it, it changes color. Its right under where it says "DOWNLOAD PRODUCT PHOTO" and "DOWNLOAD AC6 manual" . This is in the middle of the page at the top in the advertising box for the charger.
Clicking "DOWNLOAD CE FOR THUNDER AC6" lets you download a zip file that has the software for the charger.
Look again, this time read a little of it before you jump to conclusions.
