Quickbooks Licensing error

Delete damaged EntitlementDataStore.ecml file to resolve license and registration issues
Installation of QuickBooks Desktop requires one to enter a license number and a product code to perform the validation process. If the encrypted file containing the info is damaged, QuickBooks will not open and may display an error message. In those situations, deleting the entitlement file and re-entering your license and product information can help resolve the matter. For more information about QuickBooks License Error, please get in touch with us.

The following are issues and errors that may be resolved by deleting the entitlement file*:
