If QuickBooks Desktop won’t start or open, the issue may stem from several sources. Common causes include corrupted installation files, damaged company files, or conflicts with other software. Begin by restarting your computer and ensuring your QuickBooks is updated to the latest version. Use the QuickBooks File Doctor tool to repair any corrupted files. Check if your system meets the software’s requirements and confirm that no other applications are causing interference. If these steps don’t resolve the issue, you may need to reinstall QuickBooks or restore a backup of your company file. These actions should help in diagnosing and fixing the problem.
