Hello, this is Alex Poter. I am a QuickBooks software expert and have 6 years of experience in customer support. To assist in identifying and resolving technical challenges encountered during the installation process, the 'QuickBooks Install Diagnostic tool' was created. It manages and alerts you of any issues that arise throughout the QuickBooks setup process. It assists you in resolving any difficulties that are keeping you from using QuickBooks. It gives you a broad view of your system's current status.
