As you mentioned, it is very probable that it is a very old scan tool. As for not being shown under the old products link is my guess.
Here is a link from the forum with regards to your tool: http://pro.auteltech.com/autelsupport/Diagnostic%20System/261.jhtml
And here a links with a possible update offered from this web-site/company: http://www.car-tek.co.uk/visit-our-online-shop/special-offers/autel-jp701-eu702-us703-fr704-update-software-files-download
PS: If you note as you scroll down the page, there is a link for downloading the software. Plus some feedback from previous customers. And you can always contact them if possible when in doubt.
