MIDL error: 'annotation'

Recently, after upgrading Visual Studio 2005 Professional to Visual Studio 2005 Team Suite (1) I received these errors when building:

unknwn.idl(108) : error MIDL2025 : syntax error : expecting ] or , near "annotation"
unknwn.idl(108) : error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation

This post has some advice that I suppose would have worked.  However, I found that opening the SDK command prompt and running 'vcintegrate' worked just as well.

Follow these steps:

1. Start->All Programs->Windows SDK->CMD Shell
2. cd setup
3. vcintegrate -i

-----------------------------------------

(1) I just installed the latter over the former.  Perhaps I should have uninstalled Visual  Studio 2005 Professional first.
