When i right click on the database Reports -> standard reports -> disk usage getting error in sqlserver 2008 failover cluster?

When i right click on the database Reports -> standard reports -> disk usage .i am getting popup error message like below :

'The file 'Microsoft.ReportViewer.WinForms,Version=9.0.0.0,culture=neutral,publickkey token=b03f5f7f11d50a3a' cannot be opened.Do you want to remove the reference to it from the recent list?'

What can i do to see/work the reports on sql server 2008 failover?.Is there any feature missing?.What feature can i add and how on sqlserver clustering?
