Hi, My name is Alex. I have six years of customer service expertise as a certified technical executive. Are you having trouble with the QuickBooks won't open?. After you have clicked the QuickBooks icon many times, QuickBooks won't open. As a result, give QuickBooks time to load. You can also use QuickBooks Tool Hub to resolve the problem. To fix the problem, go to the tab Program Problems. Now select Quick Fix My Program from the drop-down menu. Launch QuickBooks desktop and open your data file once the application has been fixed.
