Visual Studio Common IDE Package error

I installed 2005 Beta 2 Team System today (4/17). I believe it was released
on MSDN Subscriber downloads on 4/14. I followed the uninstall procedure as
documented in subscriber downloads. Uninstall worked perfectly....seemingly,
no errors. I rebooted and installed beta2. When the IDE starts I get 6 or
so of these error messages

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