Install QuickBooks as an administrator: Right-click on the QuickBooks installation file or the QuickBooks Desktop shortcut and select "Run as administrator" to install QuickBooks with administrative privileges. This can help in resolving any permission-related issues that may be causing Error 1920.
Verify Windows user permissions: Ensure that the Windows user account you are using to install QuickBooks has administrative privileges and sufficient permissions to access and modify system files and folders.

You can do this by going to the Control Panel, selecting "Programs and Features," finding QuickBooks in the list of installed programs, and selecting the "Repair" or "Uninstall/Change" option.
Manually start QuickBooks Database Manager service: If the QuickBooks Database Manager service is not running or encountered an error, you can try manually starting the service. Go to the Control Panel, select "Administrative Tools," then "Services." Find the QuickBooksDBxx (where xx is the version of QuickBooks) service, right-click on it, and select "Start."
Clean install QuickBooks: If all else fails, you may need to perform a clean install of QuickBooks. This involves uninstalling QuickBooks, removing any remaining QuickBooks files and folders, and then reinstalling QuickBooks from scratch.
