Unable to upgrade Exchange 2010 with MB/HT server

I am receiving error in Exchange 2010 when trying to upgrade MB/HT server. The error is stating: [ERROR] This server role can't be installed because the following roles aren't current: AdminToolsRole. I successfully upgrade on CAS (Client Access Server) but not with MB and HT server. The error is occurring on the mailbox role. How can fix it?
