If QuickBooks won’t open, it’s often due to a damaged program file or a conflict during startup. Start by restarting your computer and using the QuickBooks Tool Hub to run the Quick Fix my Program tool. If the issue persists, try suppressing the QuickBooks Desktop application by holding down the Ctrl key while launching the program. Make sure your software is updated and that no background processes are blocking it. These steps usually help resolve the problem and get QuickBooks running smoothly again.
