Hello, Eatititu.

Do you have a license for QuickBooks Desktop and a product key number? Any information you offer will assist me in providing the most appropriate response to your query.

QBDT 2010 is the oldest version available for downloads. However, if you're talking about the Windows PC system requirements, this version requires a Windows 8, 7, Vista, or XP system with a Pentium 4 or higher processor running at 2.0 GHz or above.

You can start your download by going to this link: Downloads & Updates. After you've finished downloading, you can install QuickBooks by following the steps in this article: Install QuickBooks Desktop.

If you've purchased a one-time license before and you're unable to find it. You can use our license lookup tools to locate the information.

Feel free to reply to this thread if you need further assistance with the QuickBooks version and installation. Just add any details below, and I'll get back with more information.
