@brian Title says it. I ended up with two desktop icons for the Beta after installing 7.0.20280.13133 via the manual download/offline installation process. Neither the WIPs nor first beta had this issue.
Kudos on the work you’ve done on both the 6 and 7 installers. They’re both considerably faster than they’ve been in the past. Another thing I like about the 7 beta installer is that when “install” is clicked it gets right to it with immediate visual feedback that it’s working. It’s always been a pet peeve of mine that still exists with the 6 installer that it takes considerable time after clicking “install” (easily 15 seconds, sometimes in the past up to a minute) to have any visual feedback at all that my click “took”, not even a blink or color change of the install button.
