I have removed the server using control panel, and rebooted the machine. When I try to reinstall, the setup fails because of a previous installation. I am able to install the express edition, but when I try to install the management studio, I get the same failure.Any ideas?TomTue, 13 Nov 2012 18:10:00 GMTflashman-731736
