I appreciate the complete details you've shared, @LiAllPro.

Let me share additional troubleshooting steps to help you get rid of the error you've received. It's important to perform these on the main server or the computer where QuickBooks and the company files are saved. 

First, let's disable multi-user access. Here's how:

1. Access your QuickBooks  company file as the Admin.
2. Go to the File menu.
3. Select Utilities.
4. If Stop Hosting Multi-User Access is listed, choose Stop Hosting Multi-User Access.  

Now, let's create a back up copy of your company file. Then, download and install QuickBooks Tools Hub, then run the Quick Fix my Program. This is a built-in tool that auto-detects and auto-fix data damage issues within QuickBooks.

1. Download the most recent version (1.4.0.0) of the QuickBooks Tool Hub.
2. Locate the file you downloaded (QuickBooksToolHub.exe).
3. Follow the on-screen steps to install and agree to the terms and conditions.
4. From the tool hub, click Company File Issues.
5. Choose Quick Fix my File.
6. Click OK when it completes and launch your QuickBooks.

Once completed, make sure to restart QuickBooks to ensure that all components are updated. Then, you can start updating your QuickBooks software. Here's how:

1. Open QuickBooks.
2. Choose the Help menu.
3. Select Update QuickBooks.
4. From the Update Now tab, click the Get Updates button
