3. Enable Microsoft .NET Framework on Windows

Microsoft components .NET Framework 3.5 and 4.5 might not be enabled on your computer, giving way to QuickBooks errors. These components are required by the company file to run smoothly.

• Tap on the Windows + R to launch the Run window.
• Choose Control Panel, followed by OK.
• Tap on Uninstall a Program, followed by Turn Windows features on or off.
• Now, you need to verify and make sure that .NET Framework 3.5 and .Net Framework 4.5 are enabled.
• Whichever is not marked, mark them and then tap on OK.
• If they are already marked, tap on Cancel.

Now, restart the computer, launch QuickBooks, and access the company file.

4. Ensure QBCFMonitorService Doesn’t Restart on the Workstation

We need to make sure that the QBCFMonitorService doesn’t restart on the workstation.

5. Force QuickBooks to Re-Create the .ND and .TLG Files

When .ND and .TLG files get damaged, QuickBooks fails to access the company file. However, you can rename them to force QB to recreate the files.

• Navigate to the folder that contains the company file.
• Look for the files with the same name as your company file and .ND and .TLG extensions:
  • company_file.qbw.nd
  • company_file.qbw.tlg

Here, instead of company_file, you will find the name of your company.

• Right-click each of them, choose Rename, type .OLD at the end of the name and hit Enter to save the changes.

Once done, rescan the company via the Database Server Manager (if accessing the company file in multi-user mode).

Open the company file, and if you encounter the QuickBooks error 6209, 0, move to the next step.
