how to install just client libraries on windows?

hi,

i just tried to upgrade libpq.dll on windows and couldn't
work out how to do it. in the past, with 8.3.x, i knew i had
to download the entire server even though i only wanted
the client but at least i was able to install just the
client software.

now, with 8.4 (enterprisedb one click installer), i tried
to deselect what looked like server-related options and
kept the client-related options selected but the installer
kept telling me that something i had selected required
the server to also be selected. i had to unselected all of the
options before that error went away. since none of the options
was just the client library i thought there was a remote
chance that it might make some sense especially when the
installer happily proceeded with the installation process
even though no components were selected. i figured it must
know something i didn't :-)

anyway, all that was installed was the stackbuilder.
there was no PostgresPlus/8.4SS/bin/libpq.dll as i
had expected.

so, what have i done wrong? how do i use the one click
installer to just install libpq.dll? i don't mind installing
other client software along with it. i just don't want the
server installed. should i install the server and client
software and then uninstall the server software?

cheers,
raf
