Still Cant Get the Internet Working!!!!

OMG, i have still been unable to make my internet work i have tried reinstalling the bootcamp support drivers and they wont let me use then because it says i need to find out weather or not they are 32 or 64bit and i'm stupid i know very little about bootcamp and windows and mac and computers in general. I think that my version of windows 7 professional might be 32bit but the latest version of bootcamp uses like 64bit drivers? so do i need to like uninstall the latest version of bootcamp or will the older versions of bootcamp drivers work on the new bootcamp i don't know what to do this is like the 3rd day of me attempting this and could you tell me how to like uninstall bootcamp if i need to, or if i need a different version of windows.

P.S. i tried installing AirPort Extreme for windows but it didn't work either.

Please Help Me!!!!!!!!
