Welcome to the Community forum, Lorilee2.
Let me present some helpful tips so you can open and read all company files after updating QuickBooks Desktop.
Before we begin, please know that we aim to deliver customer satisfaction at all times and fix an issue as soon as possible. May I ask for additional information about how you update QBDT? I'll appreciate any further details so I can provide an accurate solution.
In the meantime, make sure the company file you want to open is a .QBW after updating QBDT to the latest release. Other file types like backups (QBB) and portable files (QBM) can't be open the same way.
You may also browse this article and try other solutions to successfully access the company file: Learn how to fix general problems when your company file won't open.
I'll keep this post while waiting for your response. Thank you and have a good one!
