The best manual for this will be the one provided in the Installation Guide. BBAdmin, one of our moderators, has also done a pre-reqs and installation guide that's a sticky in the Exchange sub-forum to this forum. But in all honesty, if you haven't read the Installation Guide, which I'm assuming you haven't, then you need to start there. This isn't just one of those things you can unzip and run setup.exe, unfortunately.
