I only started with fso about a month ago and it was confusing as hell. i got to the point where i just installed the thing by pure trial and error 
also someonr should let Turey know that most noobs who knoe thier way around a computer will see the word's Open AL pop up in the installer text and assume they don't need to install it themselves. they then proceed to wonder what the **** they did wrong.
Wait a minute...
The most recent Installer includes:
...
The OpenAL Installer (optional)
...
So Turey's installer says it installs OpenAL, but it actually doesn't?

No wonder people have trouble. I usually assume that an installer installs things, not just copy another installer to someplace else on your hard drive. That's actually more confusing to me than not installing OpenAL at all.
Not that I'm ungrateful to Turey for making the installer. Just...that's very confusing. It's the only time I've heard of a program doing that with something that's required to run it.
They're stickied. They're always at the top. They're like big, permanent announcements.
I mean, where exactly do these people look for instructions? Everyone's said that they couldn't find them at all, but no one's said where they were looking. And we can't exactly put the things where the newbs look if we don't know where they look.
I never look for install instructions for a program that has an installer. I try the installer first. That works well for nearly all programs I've ever installed for Windows. If there's big text that says "You need to do this before installing", I do that.
If there isn't an installer, then I look for installation instructions (including wiki). Then I look for a readme (possibly with the download). Then I reconsider whether I really want this program, or if I should try one of the others on the list. If I still want the program, then I'll google for install instructions. Then, if I really want to download the program, I'll look on the forums.
The reason being that many programs with no install instructions have crappy forums or a mailing list, and something on the forums is not going to be the same quality as somebody who's taken the time to take some screenshots and make a presentable web page on the subject. I would rather trust an installer by someone who cares that much to go that extra little effort, than a forum post by I-don't-know-who, that I then have to investigate whether it is or is not linked to any official source of the project in any way. (Or maybe just go on faith)
Basically what having the install instructions on a forum suggests to me that
A) nobody cares about how easy this thing is to use for the end user, which is me in this case.
B) If I ask for support, there's a good chance I'll get mediocre responses in such an exclusive or inactive community
C) The product is still very much in development and nobody believes that there is a reason to make an install guide yet.
D) The product is so buggy or hard to use that nobody sees any point to making it easy to install.
E) The community just doesn't want people to use the product, they just want developers.
F) I may end up wasting a lot of my time installing a product that I've never used only to find that I don't like it or it's hard to use.
But all this is arbitrary. If there's an installer, I install it, I try the program, and I decide for myself whether I like the program or not on its own merits, and the install process does not serve to play some role in selecting which program I use.
