QuickBooks Desktop has an EntitlementdataStore.ecml file, which contains the property license. Whenever it got damaged, and you try to access or activate the QuickBooks at that time, it shows you the 3371 error code in QuickBooks. It creates a lot of problems and does not allow you to do any work on QuickBooks Desktop. https://www.lawdeeda.com/page/delaware/wilmington/quickbooks-error-3371-status-code-11118
