If you have not decompressed the files then you can do it with the winrar program, once you have proceeded with the installation, click on the file that you downloaded from the game and put the option to say extract in/ready-set-go-sprout and that will do it. Start the download and then it will drop the file in the folder and inside if there is another folder but nothing else then you can move it to the desktop but if there are many files you should look for the one called game and run it :)
