Hey Logos !
No need to confuse him even more than he allready is.
Yes the downloads are either for 32bit versions of windows only or 64bit download which will update both the 64 bit version AND the 32bit version(64bit versions of windows run both the 32bit and 64bit IE).
When you select the download for your particular language you also need to select your windows version, in his case Windows 7 64 bit. Hope it is clear enough now for him.
Though i can't see why he just doesn't download both versions himself and just try it. Sure is faster than asking around here. I guess some folks want to be 100 percent sure before they do something, nothing wrong with that i guess.
