Hi there, @JH2.
Thanks for dropping by the Community. I'm here to share some information about using QuickBooks Desktop (QBDT) trial versions.
QuickBooks trial versions are only good for 30days. Once the trial period ends, you'll be asked to register it when you download/install it again.
As a reference, you can also check out this article for more information: QuickBooks Desktop trial links.
That should answer your concern for today. Please let me know in the comment section if you have any follow-up questions. Cheers!
