How to Fix QuickBooks Error 6010, -100

Right-click on each file and select Rename.

1. Add “.OLD” to the end of the file name. Example:

• CompanyFileName.qbw.nd.OLD
• CompanyFileName.qbw.tlg.OLD

Open QuickBooks and check if the error is resolved.

1. Press Ctrl + Shift + Esc to open the Task Manager.
2. Navigate to the Processes tab.
3. Look for processes named QBDBMgrN.exe, QBUpdate.exe, and QBCFMonitorService.exe.
4. Right-click each process and select End Task.
5. Restart QuickBooks and check if the error is resolved.

Solution 4: Reinstall QuickBooks Using Clean Install

If the installation is corrupted, a clean install of QuickBooks can help.
