I am currently running Kerio 2.1.5 on one machine and am interested in this new Ghostwall/will program. I am not x64, but am xp/sp2. Will it work x32? Kind of confused about that. I have 2 machines both xp/sp2 one pro one home neither x64. I am running Windows Live Care or whatever the MS beta thing is called, which is free at the moment, on one machine (xp pro) and running Kerio 2.1.5 on the older machine (xp home). Kerio still works ok, but this new Ghost thingy looks good and is in development, which Kerio is not. Will Ghost work on my old machine? Thanks.
