On their site driversupport.com I can't read anything about downloading their software. I even wonder if they have. What did you purchase exactly (link please from the site you read and that made you buy it).
From what I read my guess is you bought support, not software. Since that "support is provided via email, chat, phone, and remote screen sharing" I think it's best to mail or call them or find out how to chat with them.
Then they can answer your questions about what they do and how to use that.
Can you tell us what you found out?
i just purchased driver support software and they sent me a regkey but no link to install it. anyone no what to do?
