The reason is simple: there is no Windows version of Transmission. The one I showed is clearly described as "Unofficial Windows port of Transmission-Qt".
I don't understand why you need to post anything else. Have you tried the Windows installer? or perhaps it was not clear that the link (the blue, underlined text) in the second message was a link to a page that has a green button to download the installer.
I read it. I'm sorry to make you upset, and get on your bad side.
Will they ever be in the future coming up with a offical Transmission for Windows?
I thought maybe it's like with any other firewall and a BitTorrent client when I need to open the firewall to allow access? I know it's like that with Vuze, uTorrent, and ect. I'm not familiar with Linux, or anything outside of Windows.
