SMO

I developed a windows form application in visual stadio 2012 and I used SMO for backup and restoring database from SQL server 2008 R2.

When I test the application in my system that SQL server 2008 R2 & VS2012 had been installed in it, I have not problem with SMO and it's work correctly.

But when I try to install my application in another system that has only SQL Server 2008 R2, I have an Error : "Backup Operation Failed."

I have installed all of modules that required for SMO, such as :

1-SharedManagementObjects.msi
2-sqlncli.msi
3-SQLSysClrTypes.msi
4-msxml6-KB954459-enu-ia64.exe

But this solution is not cover my problem.

Please help me.
Best Regards.
