Bootcamp assistant 5 will only work on 64 bit windows 8 or 64 bit windows 7 - period!
If you're running 32 bit Windows 8, you have to download bootcamp assistant 4. version
3 or 5 won't work. Apple's grand scheme is to only support 64 bit Windows in the future. Win7
was the last 32 bit Windows that Apple will support. Bootcamp Assistant 4 is not supposed to
work with Windows 8. Apple will tell you that it was intended to only work with windows 7.
I am writing this post from 32 bit windows 8 using Bootcamp assistant 4 which is not supposed
to work, but it does. At first, Windows displayed an error screen saying that Bootcamp was
incompatible and would take a really long time to boot I replied "Run the program anyway."
If you click on help, windows will say it can't be fixed and to contact the manufacturer.
I had loaded 2 copies of Boot Camp Manager 4. Big mistake! I had to go into Task Manager Startup
and disable the second copy of Boot Camp Manager I rebooted and everything works like a charm.
So far, so good. No problems at all. I have Win8 configured so that I run everything from the Desktop
and ignore the start screen completely. I don't know if that makes any difference? My Win8 boots
up in 10 seconds, (SSD), and shuts down almost instantly. That alone makes it worth the price
of admission.
