so I checked and both RIS 2.0.1 and 2.1 where installed in my system , however, when I checked the version in VS it showed 2.0.1. I then deleted 2.0.1 , and re-started VS 2010, and the RIS about still showed 2.0.1. So I decided to also delete 2.1
and install using the one click installer. Eventually running that installer generated this:http://screencast.com/t/rKG6O4tVHuf
what's curious is that I could see the VS installer being downloaded i.e. I saw the entry in the file system for it and refreshing showing the file size incrementing , however something towards the end wiped that out i.e. as if an error was encountered and the installer totally rolled back.
