Works for me as expected. Primary group of dirs/files of "All Users" 
installed files are now local administrator (like before Feb 2012), 
including those generated by postinstall scripts (new behavior).

As already mentioned in the '--no-write-registry' thread, "Just me" 
installs only work with non-elevated user and '-B' option. Attached is a 
temporary patch I used to log changes of root_scope variable.
