download size (size of archive), not installation size.
Also has code to help fix bug #21034. Added code place holder to show the
new Additions dialog.
Fixed problem with not calculating disk space required properly. It would
not take into account components that get installed outside the user
selected folder (such as the case with security module, which needs to be
installed in a centralized place). This required the installer to be link
in nsreg_s.dll in order to tap into the Netscape registry to anticipate
where the modules might be installed at.
affects only windows.
