When you click the Repair links in QuickBooks Desktop, it typically initiates a process to fix any issues or corrupt files within the application.

On the other hand, let's utilize the QuickBooks Tool Hub to fix common problems and prevent the screen from freezing.

Please follow these step-by-step guide: 

1. Close your QuickBooks Desktop (QBDT), then download the recent version (1.6.0.3) of the QuickBooks Tool Hub.
2. Please save it in an easily accessible location and open it (QuickBooksToolHub.exe). Follow the on-screen instructions to install it, agreeing to the terms and conditions.
3. Once complete, you can access the tool hub by double-clicking the icon on your Windows desktop.

Now, let's run Quick Fix my program:  

1. In the QuickBooks Tool Hub, click Program Problems.
2. Select Quick Fix My Program.
3. Start QBDT and open your data file.

Proceed to Solution 2 in this article: Repair your QBDT.
