The portable version of 1.20 worked. The one intended for windows 98. But I'm getting some extremely slow download speeds. I tested the same torrents on my laptop with the latest version of bitcomet installed and they maxed out my routers bandwidth at 1.5 MB/s but with the older version on my desktop I only get speeds of about 300KB/s on the same torrent. My desktop has a 100mbps network card so I know that isn't the issue. In fact when I download normal HTTP files I get speeds of around a 1MB/s or more. I can't simply transfer the files from my laptop to my desktop after downloading them because my desktop only has USB 1.1 so transfers of files over 4 gigabytes can take more time then it took to download them.
