I suspect they expect you to run it on one of the DC, in this case the 
computer account is member of the domain controllers that have a lot of 
rights !

As nadya said we now this "issue" the way to do it for you is to add the 
machine account via ADSI or ldbedit to the domain admins group, it 
should do the job. Once the installation is finished, remove it from 
this group.
