The operation completed successfully, please tell Microsoft about this problem

I think by now I already installed Visual Studio 2010 Beta 2 at least 4 or 5 times but today was the first time I encountered this message:

Successful Error

In reality, VS2010 installed successfully though there was some failure installing the Silverlight SDK. I would expect this sort of result to be conveyed differently, hopefully this would change for the RTM version.

Still had a good laugh though.
