QuickBooks Desktop helps businesses manage accounting records, payroll, invoices, and financial transactions. However, installation or update problems can sometimes interrupt its normal operations. One such issue is QuickBooks Error 1920, which usually appears when the QuickBooks Database Manager service fails to start during installation or an update.

The error message may state, "Error 1920: Service QuickBooks Database Manager (QBCFMonitorService) failed to start." When this happens, QuickBooks may be unable to complete the installation process, preventing users from accessing important accounting features.

Several factors, including insufficient Windows permissions, damaged installation files, and service configuration problems, can trigger this error. In this guide, we will explain the common causes of QuickBooks Error 1920 and provide practical troubleshooting methods to resolve it.

What Is QuickBooks Error 1920?

QuickBooks Error 1920 is an installation-related error that occurs when the QuickBooks Database Manager service (QBCFMonitorService) cannot start properly. This service supports QuickBooks company file monitoring and database-related operations.

Users commonly encounter this error while installing QuickBooks Desktop, updating an existing version, or updating QuickBooks Database Server Manager on a server computer.

Common Causes of QuickBooks Error 1920

Understanding the possible reasons behind this error can help you choose the appropriate troubleshooting method. Here are some common causes:

• Insufficient Windows permissions: The installation process may not have administrator privileges required to configure QuickBooks services.
• Damaged installation files: Missing or corrupted program files can prevent the Database Manager service from starting.
• Incorrect service configuration: Windows may be unable to initialize the QBCFMonitorService because of configuration problems.
• Antivirus interference: Security software may block certain QuickBooks processes or restrict access to required files.
• Incomplete previous installation: Leftover files from an unsuccessful installation or update may interfere with the new setup.
• Folder permission issues: QuickBooks services may not have sufficient permissions to access their required installation folders.

How to Fix QuickBooks Error 1920?

Try the following troubleshooting methods to resolve the error and complete your QuickBooks installation.

Solution 1: Run QuickBooks Installation as an Administrator

Windows may restrict certain installation activities when the installer does not have sufficient permissions.

Follow these steps:

1. Close the QuickBooks installation window.
2. Locate the QuickBooks installation file.
3. Right-click the setup file.
4. Select Run as administrator.
5. Click Yes if Windows displays a permission prompt.
6. Follow the on-screen instructions to complete the installation.

Check whether the error appears again.

Solution 2: Uninstall QuickBooks Desktop

If you encounter Error 1920 while updating an existing QuickBooks version, removing the affected installation may help.

1. Press Windows + S and search for Control Panel.
2. Open Programs and Features.
3. Find QuickBooks Desktop in the installed programs list.
4. Select Uninstall/Change.
5. Follow the instructions to remove the application.

Before uninstalling, make sure your company files are backed up. Uninstalling the program does not normally delete company data, but having a backup is an important precaution.

Solution 3: Rename QuickBooks Installation Folders

Old or damaged installation files may interfere with a fresh QuickBooks setup. Renaming the relevant folders allows the installer to create new folders.

1. Press Windows + R to open the Run window.
2. Enter the following folder locations individually:
   • C:\ProgramData\Intuit
   • C:\ProgramData\Common Files\Intuit
   • C:\Users[Username]\AppData\Local\Intuit
   • C:\Program Files\Intuit
   • C:\Program Files\Common Files\Intuit
3. Locate the folder associated with your affected QuickBooks version.
4. Right-click the folder and select Rename.
5. Add .OLD to its name.
6. Repeat only for the relevant QuickBooks folders.

Note: Do not rename unrelated Intuit application folders. If multiple Intuit products are installed, make sure you identify the correct QuickBooks folders first.

Solution 4: Reinstall QuickBooks Database Server Manager

If Error 1920 appears while updating Database Server Manager on a dedicated server computer, reinstalling the affected component may help.

1. Press Windows + R.
2. Type appwiz.cpl and press Enter.
3. Locate QuickBooks Database Server Manager.
4. Select Uninstall/Change.
5. Follow the on-screen instructions.
6. Restart your computer.
7. Download the appropriate Database Server Manager installer from Intuit.
8. Install the component and follow the setup instructions.

This procedure is particularly relevant when QuickBooks Database Server Manager is installed separately on a computer that hosts company files.

To use it:
