Hello,

restore filelistonly
from disk = 'D:\GrantApp.bak'
go
restore database GrantApp
from disk = 'D:\GrantApp.bak' 
with move 'GrantApp' to 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\GrantApp.mdf',
move 'GrantApp_log' to 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\GrantApp_log.ldf'

but this gives me error as
