Error upgrading from CU7 to CU9 during install

OS: Windows Server 2012R2

Step: 13 of 17 (Installing Mailbox Service)

Any ideas? CU7 was installed and working fine. It looks it couldn't use get-wmiobject win32_operatingsystem, but I can open powershell and type this just fine and get data back?

Error:
The following error was generated when "$error.Clear();
          $a = get-wmiobject win32_operatingsystem;
          if( ([int]($a.version.split(".")[0])) -lt 6   )
          {
         stop-SetupService -ServiceName HTTPFilter
    }
  " was run: "System.Management.ManagementException: Invalid query "select * from win32_operatingsystem"".
