In a virtual pc environment, when I run the Configuration after the
installation, I get the following error:

07/13/2006 16:11:22 5 ERR Task upgradebootstrap has
failed with an unknown exception
07/13/2006 16:11:22 5 ERR Exception:

Question 1: Has ANYONE successfully run an in-place, complete upgrade
from SPS 2003 sp2 to MOSS 2007 Beta 2 ?

Question 2: What is causing the above problem? I went in and deleted
all (except the default root) managed paths prior to the install.
Still had the same error.
