Minecraft transfer to another PC?

Alright. Here is the pickle i'm caught in.

I have a computer running Windows 7 that has internet connection and minecraft, I also have a Windows Vista computer that does not have Wi-Fi or minecraft. I have a 2 gb SD card and i tried to get the minecraft.net version and the Anjo Cadio version, and neither seem to work. Am i doing something wrong?

Any suggestions? And, aside from the other question, are their any products that can allow my pc to gain Wi-Fi connection?

Its an SD card, not really made for transferring stuff, made for backing things up, if you want to transfer something, grab a USB 2gb from walmart or target, maybe 10-15$
