QuickBooks Error 3371 Status Code 11118: What It Means and How to Fix It (2026)
Quick Answer
Error 3371 means QuickBooks cannot load the license data, usually because the EntitlementDataStore.ecml file is damaged. Deleting this file and re-entering your license key resolves it in most cases.
What Error 3371, Status Code 11118 Actually Means
Error 3371 with Status Code 11118 is a licensing and activation error. QuickBooks stores license data in a file called EntitlementDataStore.ecml. When this file becomes corrupted (often after a Windows update, hard drive error, or improper shutdown), QuickBooks cannot validate your license and refuses to open.
Common causes:
- The EntitlementDataStore.ecml file is corrupted
- A Windows update changed the file permissions or encryption on the license file
- The hard drive has bad sectors in the area where the license file is stored
- QuickBooks was moved to a new computer without proper license deactivation

Delete EntitlementDataStore.ecml
Navigate to C:\ProgramData\Intuit\Entitlement Client\v8\ (or v6 for older versions). Delete the EntitlementDataStore.ecml file. This folder may be hidden — enable "Show hidden files" in File Explorer.
Re-register QuickBooks

If registration fails, use the manual method
Press F2 in QuickBooks to open Product Information. Note the license and product numbers. Close QuickBooks. Delete the ecml file again. Reopen and enter the numbers manually.

Frequently Asked Questions
Where do I find my license number?
Check your original purchase email, the sticker on the QuickBooks box or disc, or your Intuit account at camps.intuit.com. Press F2 inside QuickBooks if it opens partially.
Can I use QuickBooks without activating?
QuickBooks allows limited use (usually 30 days) without activation. After that, it locks you out until you activate. Error 3371 can appear before or after this grace period.
Will I lose my data if I delete the ecml file?
No. The EntitlementDataStore.ecml file only contains license information. Your company file data is completely separate and unaffected.
Why did this happen after a Windows update?
Windows updates can modify file permissions and encryption in ProgramData. The ecml file uses local encryption that is sensitive to these changes.
Does Hubricon require a QuickBooks Desktop license?
Hubricon works with QuickBooks Online, which does not have local licensing or activation issues. If you use QuickBooks Desktop, Hubricon can still read your data via the QBO API after you sync your desktop file.
