Dynamics CRM 2013 “Orion” installation error

Hello friends,
I need this Microsoft Dynamics CRM Server in the computer when I am in process, I got an error message. The installation went almost to the end, but it failed leaving an error message. It says some tools failed and access denied. How to fix the issue? Friends suggest me some idea to overcome this error. Thanks.
