Latest Date: January 9, 2026

Users witness the following errors due to incorrect validation code:

  • The system displays: “The validation code is incorrect, or the service is temporarily unavailable.”
  • The system displays: “You cannot use online banking because QuickBooks is not registered.”
  • The system displays a prompt to subscribe to the Accountant’s Copy File Transfer Service.
  • The system displays a grayed-out Sync License Data Online option.
  • The system displays an incorrect validation code message.
  • The system displays an ‘Incorrect License or Product Number’ message.

This guide explains how to resolve the “Validation code is incorrect” error. Follow the steps in the given order to resolve the issue and reinstate regular QuickBooks Desktop operations.

Key Points to Check Before You Follow Any Suggested Fix

Users confirm all license information before implementing any solution. These verifications ensure accurate validations and prevent repeated activation issues in QuickBooks Desktop.

Here are the important points to review before implementing any solution:

  • Users check the license number plus the product code while installing.
  • Users confirm the information in the confirmation email sent by Intuit.
  • Users need to review whether QuickBooks Desktop is active and running.
  • Users match the license number and product version with the package sticker.
  • Users review the CD package sticker when the installation requires a CD.

How to Resolve the Incorrect Validation Code Error?

To resolve the incorrect validation code issue, implement the following solutions in order:

1. Confirm the Time and Date Settings

Users implement this solution when wrong system time settings prevent activation. Right time settings guarantee correct validation during the activation of QuickBooks Desktop.

Here are the steps to verify the time and date settings:

  • Shut down QuickBooks Desktop and exit all company files.
  • On the Windows Taskbar, right-click the time display.
  • Now, choose the “Adjust date/time” option.
  • Now, click the “Date and Time” tab and choose the right date for the present year.
  • Choose the “Apply” button.
  • Now, select the “OK” button.
  • Next, open QuickBooks Desktop and choose the “Help” button.
  • Now, click the “Activate QuickBooks” button.
  • Now, click the “Activation” button.
  • Add the validation code and choose the “Next” button.

2. Reboot the .ecml file

Users implement this solution when corrupted entitlement data restricts QuickBooks Desktop from checking the license. Removing the EntitlementDataStore.ecml file compels QuickBooks to create new license data.

Here are the steps to reset the .ecml file:

  • Shut down QuickBooks Desktop.
  • Ensure all the QuickBooks processes are not inactive.
    • Click the “Ctrl” + “Shift” + “Esc” keys. This will open the Task Manager.
    • Choose the “More Details” option in Windows 10.

    • Mark each QBW32.EXE instance and choose the option “End Task“.
  • Click the “Entitlement Data Folder“.
    • Click the “Windows” + “R” keys to start the Run screen.
    • Open the folder:
      C:\ProgramData\Intuit\Entitlement Client\v8
      (Use v6 for older QuickBooks versions.)
    • Click the “Enter” button.
  • Erase the .ecml file.
    • Right-click the “EntitlementDataStore.ecml” file and choose the “Delete” option.
    • Choose the “Yes” button to verify that the file is erased.
    • Click the Company file and finish the registration when you are notified by QuickBooks.
