How to Fix QuickBooks Error 3371 — Complete Step-by-Step Guide

QuickBooks displays: "Error 3371, Status Code -11118: QuickBooks could not load the license data. This may be caused by missing or damaged files."

Error 3371 means QB's license data file is damaged, missing, or references the wrong hardware configuration. At QuickFix Bookkeeping, 3371 has one targeted fix that Intuit specifically documents: deleting the EntitlementDataStore.ecml file forces QB to recreate fresh license data. This file, not the company file, stores the license validation. Your company data is completely unaffected.

The EntitlementDataStore.ecml Fix — Why It Works

EntitlementDataStore.ecml is QB's local license cache file. It stores the validation data QB uses to confirm the license without contacting Intuit's servers on every startup. When this file is corrupted, damaged, or was created on different hardware, QB can't validate the license and shows Error 3371. Deleting it is completely safe — QB immediately creates a fresh copy on next launch and re-validates the license against Intuit's servers. Your QB license is not revoked — only the local cache is cleared. The file is at: C:\ProgramData\Intuit\Entitlement Client\v8\EntitlementDataStore.ecml

3

Open QB as Administrator: right-click QB → Run as Administrator → QB opens and re-creates the EntitlementDataStore.ecml fresh → enter your license and product number if prompted → Error 3371 should be gone.

METHOD 2Run QB Install Diagnostic Tool3371 persists after deleting ecml file

Tool Hub → Installation Issues → QuickBooks Install Diagnostic Tool → run → restart → open QB as Administrator. The diagnostic tool repairs QB's installation components including the entitlement client that manages the ecml file.

METHOD 3Clean Reinstall QB3371 persists after all above
1

QB Clean Install Tool → uninstall QB → delete C:\ProgramData\Intuit\Entitlement Client\ entire folder → reinstall QB from a fresh download → run as Administrator → re-enter license number when prompted. Your company files are stored separately and are unaffected by this reinstall.
