In such a scenario when Quickbooks won't open , restart your system and QuickBooks application. If you still face the issue, try to fix it by suppressing the QuickBooks desktop application. For that, press and hold the Ctrl keys and open the QuickBooks application. Release the Ctrl key only when ‘No company open’ appears. Now, open a company file and select Open. It will help you find if the error is associated with your QuickBooks data file.
