Yeah, I always face with that problem.

A quick reply on 0.47pre2 Win32 installer.

After running the installer I got a warning that previous version of Inkscape is already installed (see attached screenshot 1), but that file "Uninstal.dat" is missing. In my case the installer was pointing to the directory where I installed some development version with this "new" installer (I believe it was version "inkscape-win32-r22047" from "http://inkscape.chrismorgan.info/win32-builds/", but I'm not completely sure about the version).

However, I chose the same directory and in the next step it asked me if I want to uninstall the old version before I install this one (0.47pre2). I chose YES, and the old version was uninstalled, except the file "Uninstall.exe", which was left in the folder. But I think I had that folder opened in Total Commander, and this might be the reason that this file wasn't deleted. Furthermore, I have also noticed that the uninstallation deleted uninstall entries in "Add or Remove Programs" for the official 0.46 version. The program files however were of course still installed in Program Files and everything was working.

Anyway, then it started installing version 0.47pre2 and I got warning that the chosen folder is not empty (see 2nd screenshot). Than no matter what I clicked (CANCEL or RETRY), nothing happened, i.e. it didn't install nor cancel the installation (the info box stayed on the screen even after several clicks). The only thing that helped was manually deleting file "Uninstall.exe" in the installation folder, and the installation went on without problems.

These are my experiences, but at the end basically everything works as expected.

Rok
