xp pro vs home edition

While in a pc with xp pro I could update Comodo firewall from the version 2.4 to 3, in a pc with xp home the updater says “there are no update available”.
Comodo 3 does not support xp home edition?

Hi zippo

The updater from v-2 to v-3 has temporarily been turned off I believe. If you would like to use version 3 please uninstall version 2 and download version 3 to install it.
