Hi Juan,
A) You can't download it, at least not yet.
B) Even if you could, I doubt that you could install it to Vista as it is
already a system component.
What issue are you encountering with it that you believe reinstalling would
solve?
Have you run the system file checker yet to check for integrity?
Tried the installer cleanup utility?
