QuickBooks Error 3371: What It Means & How to Fix It

Quick Fix: This error means QuickBooks can't read your license data — the file that stores your registration info got damaged. Delete the EntitlementDataStore.ecml file and reactivate QuickBooks.

What Causes Error 3371?

The full error usually reads: "Could not initialize license properties. Error 3371, Status Code -11118"

1. The EntitlementDataStore.ecml file is damaged — This file stores your QuickBooks license and registration info. If it gets corrupted (from a crash, Windows update, or failed QuickBooks update), QuickBooks can't validate your license.
2. Recent hardware or Windows changes — Replacing a hard drive, upgrading Windows, or even changing the system date/time can invalidate the stored license data.
3. MSXML component is damaged — QuickBooks uses Microsoft XML (MSXML) to read the entitlement file. If MSXML is broken, QuickBooks can't parse the license data even if the file is fine.

How to Fix QuickBooks Error 3371

Method 1: Delete the EntitlementDataStore.ecml File

This is the fix that works for most people:

1. Close QuickBooks
2. Open File Explorer and navigate to:

- C:\ProgramData\Intuit\Entitlement Client\v8 (or v6, depending on your version)

- Note: ProgramData is a hidden folder — type the path directly in the address bar

1. Find EntitlementDataStore.ecml and delete it
2. Open QuickBooks — it will ask you to reactivate
3. Enter your product and license keys (check your purchase email or the sticker on your QB CD case)

Method 2: Run QuickBooks Install Diagnostic Tool

1. Download QuickBooks Tool Hub
2. Open it → Installation Issues → QuickBooks Install Diagnostic Tool
3. Let it run (it repairs MSXML and other components that cause this error)
4. Restart your computer and open QuickBooks

Method 3: Re-register QuickBooks

1. Close QuickBooks
2. Press Windows + R, type this and press Enter:

1. Wait a moment (no visible output is normal)
2. Open QuickBooks normally

Method 4: Reinstall QuickBooks Using a Clean Install

1. Uninstall QuickBooks from Control Panel
2. Run the QuickBooks Clean Install Tool (under Installation Issues)
3. Restart your computer
4. Reinstall QuickBooks
5. Activate with your license key

Still Getting Error 3371?

• Check if your license key is valid — if you bought QuickBooks secondhand or from an unauthorized reseller, the license may be blocked
• Contact Intuit Support — they can validate your license and reset your activation remotely
• If you've changed computers, you may need to deactivate QuickBooks on the old machine first (or call Intuit to transfer the license)

Prevent This Error in the Future

• Keep your license and product keys saved somewhere safe (email, password manager, etc.)
• Don't modify files in the Intuit folders manually
• Create a restore point before major Windows updates — these can occasionally corrupt the entitlement file
• Keep QuickBooks updated — newer versions handle license validation more reliably
