Thank you for posting your concern here in the thread, Roberta12.

Are you having the same issue with the initial post? If so, make sure you're the master admin when updating the QuickBooks Desktop (QBDT).

If you're already the primary admin and getting the same prompt message, I suggest following the suggested troubleshooting in the thread first.

If you've already performed these suggestions, then you can proceed to uninstall and reinstall QBDT to fix the issue. For troubleshooting steps, you can visit @FateCandylaneT's post in the thread.

Additionally, if you want to maintain your software up to it's latest release, you can refer to this article: Update QuickBooks Desktop to the latest release.

Keep in touch if you have further questions about the product in QBDT. I'll be sure to get you back promptly.
