I have this in http://git.gnome.org/browse/tomboy/tree/Setup/Setup.wxs

<Condition Message="This setup requires Gtk# for .NET (version 2.12.8 or higher). Please download the latest installer from http://ftp.novell.com/pub/mono/gtk-sharp/ ">
	<![CDATA[GTKSHARPNOVELLINSTALLVERSION >= "2.12.8" OR REMOVE ~= "ALL"]]>
</Condition>

Now unfortunately, because this version check is
a string comparison, when GTKSHARPNOVELLINSTALLVERSION
is "2.12.10", that does not pass the >= "2.12.8" test.

I'd like to do a more elaborate check...maybe I could
check that if the string starts with "2.12.", and the
string length is greater than 6?

I'd like to make sure that we don't allow install
with gtk-sharp < 2.12.8 if it's not too hard.

GTKSHARPNOVELLINSTALLVERSION >= "2.12.8" OR
(GTKSHARPNOVELLINSTALLVERSION << "2.12.1" AND GTKSHARPNOVELLINSTALLVERSION <> "2.12.1") OR
REMOVE ~= "ALL"

That should at least work until we release 2.12.20. ;)

Thanks! I've always had trouble reading through wix/msi docs. This one was clearly stated here but I had trouble finding the page:

Your fix works great!
