I have a SQL 2005 db I am attempting to restore a SQL2008R2 SP2.

RESTORE DATABASE [Db] 
FROM  DISK = N'C:\temp\sql\DB.bak' WITH  FILE = 1,  
MOVE N'DB' TO N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\NewDB.mdf',  
MOVE N'DB_Log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\NewDB.ldf',  
REPLACE,  STATS = 10
GO

But It keeps giving this error.

Msg 3634, Level 16, State 1, Line 1
The operating system returned the error '5(failed to retrieve text for this error. Reason: 15105)' while attempting 'RestoreContainer::ValidateTargetForCreation' on 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\NewDB.mdf'.

I am logged into SQL as SA. I have Admin permissions on the system. I have also tried to remove the restore location to another path (that has full permission) with the same error.
