SQL install fails with error: The account that is running SQL Server Setup does not have the right to back up files and directories, the right to manage auditing and the security log and the right to debug programs.
The domain admin on the server will need to make these changes. The changes cannot be made at the local user level.
The relevant passage from this web site:
"This user right is defined in the Default Domain Controller Group Policy object (GPO) and in the local security policy of workstations and servers."
