Clean up Beta1 install before installing Beta2
Just found this link… looks I thought I had Beta1 removed from my machine but it found some Sql stuff laying round… If you are having trouble with your Beta2 install, try this out and see if it helps.
The auto uninstall tool at http://go.microsoft.com/fwlink/?linkid=47065 (this also does Framework clean up)
