Resolving failure to license error code 4-1

To resolve failure to license error code 0-0, you need to rebuild the license files.

Rebuilding the license file:

  1. Close ProSeries.
  2. Open Windows File Explorer.
  3. Browse to the following location: C:\ProgramData\Intuit\EntitlementClient.
    • ProgramData is a hidden folder. To view it, you may need to open Control Panel, then select File Explorer Options. Click the View tab, and check the box Show hidden files, folders, and drives.
  4. Open the v8 folder.
  5. Right-click on the entitlementdatastore.ecml file, then select Rename.
  6. Type old at the end of the file name, so that it reads entitlementdatastore.ecmlold.
  7. Open ProSeries.
  8. From the Tools menu, select License Products.

The entitlementdatastore.ecml file contains the license information for ProSeries 2015-Current as well as QuickBooks Desktop. To re-license prior year ProSeries programs go to the Tools menu and choosing License Products. If you use QuickBooks you will need to go to the Help menu and choose Activate QuickBooks Desktop.  

If the error persists, please contact ProSeries Customer Service to verify your ProSeries entitlements on the correct account.
