I am using a clean install of windows 7, with visual studio 2010(sp1) and biztalk 2010, and SQL Server 2008 R2(sp1). From Visual Studio, when I try to 'Add a Generated Item' and then 'Add Metadata Adapter' for a SQL adapter, the wizard window disappears just before the wizard is complete. Googling online, I found this is often an issue with MSXML, so I installed MSXML 4 but this did not fix the problem. Downloading the Adapter pack and getting new(er) adapters is not an option for me. Any ideas what might be causing this?
