Occasionally, third party applications, such as anti-virus and anti-spy ware programs, can interfere with the successful installation of QuickBooks Desktop. As a result, it may be necessary to install QuickBooks Desktop in a special diagnostic mode of Windows called Selective Startup. Selective Startup mode enables you to start Windows while selecting which specific items to run.
QuickBooks uses the Microsoft Windows Installer, which requires the Windows Installer Service to be active during the installation. Since running Windows in Safe Mode deactivates the Windows Installer service, it is no longer an option for troubleshooting potential third party installation conflicts for QuickBooks Desktop.
