I've installed the application and checked the details about it and doesn't appear to use an accounting software. The software is also available for downloading from its official website as well. I've installed it, and according to what they've said, AutoQuote is working as a standalone application.
You can download it as well from the following link: http://nl.aq360.com/updates/aq%20setup.exe
