While attempting to restore a damaged data file, the data file was partially updated in a previous version, or the data file was damaged in a previous version. QuickBooks displays the message:
This data file cannot be used because it was not completely updated. Please restore your backup.
This error occurs when the file is damaged by upgrading to a later version of QuickBooks and aborting the process before it was completed, or existing damage to the file causes the update to fail.
If you believe that the file has been partially updated from a previous version, restore the backup created during the upgrade process to the previous version of QuickBooks used to open the file.
If you do not believe the file has been damaged while attempting to update from a prior version, see Data damage diagnosis and repair for steps to resolve your issue.
