I installed SQL Server 2008 R2 Nov. CTP on a W2K8 R2 server. I then installed only the SQL Management Studio on another W2K8 R2 server. From both servers, when I try to run any Management Studio report, I receive a pop-up window stating "The file 'Microsoft.ReportViewer.WinForms, Version=188.8.131.52, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' cannot be opened. Do you want to remove the reference to it from the Recent list? There are Yes/No buttons, regardless of which button I press nothing good happens.
