A required privilege is not held by the client

When attempting to perform modification of the registry hive of a Domain Controller in a SureBackup Job, VDK encounters an error. You can successfully mount and modify the hive, but when you try to save it, the following error occurs:

<01> Info     Execute VDK command: close * /F

The issue may be caused by lack of permissions for the service account, under which the Veeam Backup Service runs in the Local Security Policy.
