Install fails on Macbook Pro 10.8.3

I have tried a few time to install the software, but once the install progress gets to "Connecting", the install halts and I get no further activity. Forece Quit the application reveals nothing in the Application folder, and a reboot does not seem to any changes to my system. Trying to install again gets me back to a hang in "Connecting". Thanks for any help.

I tried to mention this whilst 10.8.3 was a developer preview.  Did not get any e-mail reply though.
