SQL Mgmt Studio Error - Class does not support aggregation...

One of our developers sent me the e-mail below. I Googled the message and found a post that said to "Remove Workstation componenents, then do a repair on Net Framework 2.0 then Re-Install workstation components." That seems pretty dramatic. Has anyone run into this and what did you do to fix it?

I get quite a few messages when I try to do any type of development in SQL 2005. For example, I selected VIEWS, NEW VIEW and got this message:

TITLE: Microsoft SQL Server Management Studio

Class does not support aggregation (or class object is remote) (Exception from HRESULT: 0x80040110 (CLASS_E_NOAGGREGATION)) (Microsoft.SqlServer.SqlTools.VSIntegration)
