everytime i want to download something it says i need windows 32 where can i get this for free and how can i download this plz help

The mac is telling you that its a win32 file which means you need to run it in a windows operating system. What you can do though is install windows on your mac as a dual boot, which means you can have two operating systems installed but only run them one at a time. There is a program in your finder apps>utility called bootcamp that does this for you. But you will need a windows install disk.
