If you have beta POV-Ray for Windows v3.1 beta 6 installed, this is all you
need to update to beta 6b.
ftp://ftp.povray.org/pub/povray/beta/beta3.1-6b/winupd.zip
Just unzip it into the <installdir>\bin directory.
If you downloaded a version of 6b that complains about a missing DLL, then this
update will also fix that.
