lots of Windows problems (pygtk)

I've written a nice pytgk application (under my Gentoo). Unfortunately 
the client uses Windows (XP Professional SP2) on his workstations. I had 
a horrible day when trying to install the pygtk environment on those 
Windows: python and pygtk -- it's easy (installers from: 
http://www.pygtk.org/downloads.html), unfortunately installing the GTK+ 
resulted in numerous errors about missing libraries on selected 
workstations when running my application (for example: 
lib-glib-2.0-0.dll and lib-gio-2.0.-0.dll). The most annoying thing was 
that the workstations were +/- the same -- on some it worked fine, on 
some -- didn't. After a few tries I decided not to use any installers 
(like: http://sourceforge.net/project/showfiles.php?group_id=98754) and 
install the GTK+ manually from the official "bundle" 
(http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.12/gtk+-bundle-2.12.9.zip) 
-- unzip it into C:\GTK and then manually add C:\GTK\bin to the PATH 
variable. It worked on most workstations -- unfortunately there were 
some it didn't. I suppose some conflicts with previously installed 
windows programs that used the GTK+. Sometimes deleting the GTK+ 
directory, cleaning the registry (deleting any *gtk* keys and values) 
and reinstalling the GTK+ helped. Sometimes -- not... :-(

Are there any tools or procedures for troubleshooting GTK+/Windows 
installations? resolving GTK+ conflicts among different Windows 
applications? Is there any database of GTK+/Windows errors? Or -- at 
least -- any procedures than can identify Windows workstations that can 
be "tricky". Today it looked quite randomly... :-(

Best regards,
Marek
