In my work I made backup of database and I receive file .bak. Now I would like restore this database in my machine. But I get the following error:
Cannot open backup device 'C:\Program Files...\MSSQL10_50.SQLEXPRESS...\file.bak'.
Operating system error 5(failed to retrieve text for this error. Reason: 15105).
RESTORE HEADERONLY is terminating abnormally. (Microsoft SQL Server, Error: 3201)
Of course I searched the Internet, for example: http://social.msdn.microsoft.com/Forums/sqlserver/en-US/805661f1-cf23-4230-ae31-d9cc16505359/cant-restore-backup-from-2005-to-2008r2?forum=sqlexpress
But all users have permissions to all folders so I'm really confused. What is the problem?
