The task that you are trying to run was created under a different account and you do not have enough privileges to run it
This article applies to:
E00640067: Failed to run the task
Failed to execute the task script. Error #1314 - "A required privilege is not held by the client (0xFFF0)
code = 80070522
Tag = 0xBD28FDBD64EDB8AF".
(!) Other operations may also fail with this error message. The solution will be the same as described below.
The most probable cause is that the task was created under a different Windows user account (even it had Administrator rights). The account under which you are trying to run the task does not have enough privileges for the operation (even if the account has Administrator rights).
The issue should now be resolved.
