• Now, click on Check for updates.

2. Run the QuickBooks Install Diagnostic tool

If something went wrong during the QuickBooks install, it could cause problems when you try to use it. Run the QuickBooks Install Diagnostic Tool to fix common install issues and QB error code 1406.

Note: Download and install QuickBooks Tool Hub (1.6.0.8) to the latest release. This lets you run the different tools to resolve different issues.

3. Configure Windows Firewall for QuickBooks Desktop

Windows Firewall is a security application that manages system ports for incoming and outgoing data and protects you from malware, viruses, and cyber-attacks. If it detects any issues with QuickBooks Desktop, it may block the necessary ports and software processes from running. To resolve this, create Windows Firewall port exceptions for QuickBooks Desktop. 

4. Temporarily disable the system security application

If creating ports for QuickBooks Desktop in Windows Firewall does not resolve the QuickBooks installation error 1406, try temporarily disabling your system’s security applications. This includes the Windows Firewall and any installed antivirus or anti-malware programs. After troubleshooting, remember to re-enable all security features to keep your system protected.

5. Manually repair the Windows components
