Just downloaded Inkscape-0.47pre2-1.exe and am trying it out.
Please consider modifying the installer to provide an option to allow one to install in an existing directory that has files and subdirs. The use case for this request is that I customize the Inkscape theme on my systems and therefore have content in etc, lib, and share subdirs.
I think a "safe" solution is to provide an "Overwrite!" button in the dialog that pops up when you try to install to a non-empty dir. Keep the "Retry" and "Cancel" buttons and default to not allowing one to install to a non-empty dir, just provide us of those who have existing customizations the option of continuing the installation without having to waste time copying the customizations to a temp directory and then copying them back.
Thanks, and THANKS for all the coolness that is Inkscape!
