I used the downloader from the site here. I don't recall seeing any mention of version compatibility.
I have W7 Ultimate 64bit and it installed just fine.
I remember hearing about an issue with some installers for applications (symantec a/v for example) that didn't pick the correct installer service in a windows 64 bit system and would have a similar result.
If you used your browser to download the client (instead of fileplanets download manager) there's a good chance it stopped at 2GB. This is a limitation of 32bit browsers.
Use the downloader H4z mentioned, or if you already have a torrent client you can get just the torrent file floating around here somewhere.
