Hi,

when I right mouse click on a certain maintenance plan and choose Modify,
The follow error popped up in a dialogue box.

---------------------------------------------------------------
Unexpected error: service
'Microsoft.VisualStudio.Designer.Interfaces.INVSDDesignerService' is not
available.
Make sure that the product is installed properly. (mscorlib).
----------------------------------------------------------------------



Also on the server machine, we installed management studio for 2008, when we
expand the management menu, there is no 'Maintenance Plan' item listed.

Please kindly advice what to do in both situations.

Pingx
