I'd like to share some information, DjTrex.

For the trial links, we only have the latest version. You can check out this article for more details: Download a trial of QuickBooks Desktop.

If you have the QuickBooks Desktop license and want to upgrade to the latest version, you'll want to go to this link to download the 2012 and 2015 versions: Downloads & Updates.

Otherwise, look for you license here: Locate Your License or Product Number.

Please don't hesitate to comment on this thread if there's anything else you need. Thanks.
