Beyond this -

Could be but it's not a common one.  I just installed 1.7 last night (on XP) 
without
this problem and this is the first report to the list of it.

Of the top of my head, the only things I can think of trying are:

   1. Use Process Explorer (or handle.exe from the same guys) to see what
     else has anything along the line of '/etc/setup/setup.rc' open, both 
before
     the install and at the time of the problem.

   2. Try making '/etc/setup' before the install.  Make sure you have access to
      this (i.e. verify you can make 'setup.rc').
