Cannot get backup script to execute

Im getting an error 5 Access Denied when I am trying to restore the adventureworks database in SQL Server 2014.  Here is the script:

USE [master]
RESTORE DATABASE AdventureWorks2014
FROM disk= 'C:\TestBackup\AdventureWorks2014.bak'
WITH MOVE 'AdventureWorks2014_data'
TO 'C:\Program Files\Microsoft SQL Server\MSAS12.MSSQLSERVER\OLAP\Data\AdventureWorks2014.mdf',
MOVE  'AdventureWorks2014_log'
TO 'C:\Program Files\Microsoft SQL Server\MSAS12.MSSQLSERVER\OLAP\Data\AdventureWorks2014.LDF'
