Just to clarify things a bit.
On the above support article, it says, "Use the Boot Camp Assistant to download Boot Camp 5 (only available on OS X Mountain Lion v10.8.3 and later). Boot Camp 4 is available via Boot Camp Assistant for earlier versions of OS X (OS X Mountain Lion v10.8.2 and earlier). "
From that I deduce that Boot Camp Assistant 5 cannot automatically download Boot Camp 4 for ML 10.8.3. However, it goes on to say that one can download both Boot Camp 5 and 4 from the support downloads page.
Is it possible to download Boot Camp 4 manually and use it with my ML 10.8.3 Boot Camp Assistant?
