Although the SOS installer insists the program is not compatible with Vista… it STILL is. I use innoextractor to extract the changed files and replace the existing older ones and restart and it runs just fine. Only fault I find with the program is the torrent client is a leech and cannot be configured to seed beyond the completion of the download like a real torrent client this means people will get to recognise the torrent client name and may decide to block the non-seeding client from being shared with as it behaves with bad torrent etiquette.
