Thanks for the information,

I am a bit uncertain about what you mean.

You said, "grab the current setup.exe"

Do you mean download the most recent one, or one from another machine
with an internet connection?

You said, "take both to the machine which you want to update"

Which "both" are you referring to? There is the one from, "grab the
current setup.exe", what setup.exe is the other half of "both", or am I
not getting that quit right?

You said, "point setup*.exe at the mirrored packages"

What do you mean by "mirrored packages"?

I assume that what you need to do is to copy over the install directory
from a more up to date installation, meaning the directory with the
mirror folders like,

and select one of these as the local package directory. Is that what you
mean? If so, should I use the most recent setup.exe or the one in the
existing installation (the one I want to update)?

How do I make sure that noting other than ruby gets updated?

I will back up the existing installation first in case I manage to bork
the thing.
