Solution 2

Few thing s to check:
- does the mdf file actually exist in that location
- do you (actually the SQL Server service) have necessary privileges. In windows 7 program files directory is more protected so also you can try placing the database file somewhere else and see if it works. (Something like c:\database\...).
