Hi friends my name is Alex Poter, and I am a QuickBooks technical help expert. If your QuickBooks file doctor is not working then, Go to the "File" menu, then "Utilities," and then select "Repair File and Network Problems." When the resulting dialogue box displays, select the OK option. When you use the QuickBooks file doctor, the application is restarted with administrator privileges. When the confirmation dialogue box displays, click the Yes button.
