Restoring A Backup

If after restoring the backup the file needs to be upgraded, you must use the Admin user login/password.

In my experience, if there is more than one user saved in the file, then you'll get a login dialog with two fields regardless of the reason the login dialog is being displayed (opening a file; restoring; opening and upgrading;...)

If there is only one user saved in the file, then the login dialog will have only one field for the password, because you don't need to enter the user name (which is the admin user.)

I've got steps to help ensure you can restore your backup file,@REVCPA54.

In addition to brconsultingid2's answer, issues like this can be resolved by running the QuickBooks Tool Hub. It also helps fix other errors such as:

• errors 6123 and H202.
• Install issues or errors and networking errors.
• PDF and printing errors and QuickBooks crashing.

For the best experience, I recommend using Tool Hub on Windows 10, 64-bit. Once ready, here's how to proceed:

1. Close QuickBooks Desktop, and then download the most recent version (1.4.0.0) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). 
2. Open the file you downloaded (QuickBooksToolHub.exe), and then follow the on-screen instructions to install and agree to the terms and conditions.
3. Once done, double-click the icon on your Windows desktop to open the tool hub.
4. In the QuickBooks Tools Hub, choose Program Problems.
5. Select Quick Fix my Program, and then open QuickBooks Desktop (QBDT) and log in to the company file.

Then, restore your backup file again. If the same thins happens, proceed to Solutions 2 and 3 of this article for the troubleshooting steps: Fix Admin user error in QBDT.

Just in case you encounter company file issues, you can verify and rebuild your data to fix it. Click this resource for more details: Verify and Rebuild data.

I'm always around to lend a hand if you have more questions about managing your data or anything else related to QuickBooks. Take care and have a great day.

Hi @REVCPA54 , how about contact your admin user or you log in as admin user then change user name and password. Some times doing that was helpful or you could use quickbooks tool hub (click here) .
