What to Do If QuickBooks Has Stopped Working
                     Why does QuickBooks 
Desktop Has Stopped 
Working?
There are two main reasons why your QuickBooks program stopped working suddenly: 
either a damaged Windows operating system or issues with the QuickBooks installation.
If your QuickBooks has stopped working suddenly after updating the program; it means 
the installation is damaged. However, if this was not the situation; you need to fix the 
Windows operating system. So, to fix the both issues in one go; we suggest you run the 
QuickBooks Install Diagnostic tool. But before moving further, you need to download and 
install the most recent version of Tool Hub. Let’s see how can you do so:

• Exit QuickBooks and go to Intuit’s official site.
• Download the Tool Hub in its most recent version 1.6.0.3 and save the 
downloaded file in an easily accessible location.
• Now, open this file QuickBooksToolHub.exe by double-clicking on it.
• Adhere to on-screen steps and agree with the terms and conditions to start 
the installation.
• Once it's installed, double-click on the Tool Hub to open it.
Now, let’s run the QuickBooks Install Diagnostic Tool if your QuickBooks Has Stopped 
Working
• Go to the Installation Issues menu and then click on the Run QuickBooks Install 
Diagnostic Tool button.
• The tool might take time to fix the installation issues in QuickBooks as well as 
Microsoft Components. Let it run until then.
Once done, try again to launch the program and make sure QuickBooks works properly.
