Supply and demand would seem to indicate the solution would be for you (being the one who needs the program) download winrar to unpack the download provided for you, instead of us (being the ones who have winrar and thus don't need a .zip file) devoting additional work and web space just because you're too lazy to unpack a file. Does your mom cut your food for you too? Sorry, but this sort of thing just gets on my nerves. What's next, people actually asking us to google for them? Oh wait, they already are... -_-
You have the file you were looking for. Rejoice. Then keep the real archiver on your hard drive, because Windows' built-in zip explorer won't last you long in the web wide world.
