Need instructions and tips on installing a home tv projector.
Answer
Yeah... we are going to need a bit more information for that. Say at least the brand and model; though it should have come with a book that tells you this.
Installing a home tv projector varies greatly between a portable LCD/DLP unit or a CRT unit. Cables and inputs also matter, as you may or may not be able to run your audio through the projector, or you may have to buy various adapters for video inputs.
The setup you want also makes a difference; did you want to hang it upside down or are you simply putting it on a shelf thats attached to the wall. I find LCD/DLP can go on a shelf, but you certainly wouldn't want a CRT unit on a shelf.
Darknight: Hate to break it to you, but you are the neophyte here. (It's not spelled neophite; you could at least get that correct). A CRT projector is one that uses CRT tubes rather than a bulb and LCD or DLP technology.

There is a picture of one for you and yes I know he was talking front projection. They are traditionally not used too much anymore as they are obviously very big and very heavy. They are also expensive, very expensive to buy but they do last quite long and you don't have a few hundred bucks on a bulb every time. They also don't have a native resolution as is with any CRT.
Brand and model are of course relevant; it's much easier to figure out where the mount holes are (and trust me, it's a big difference between those little things best buy sells vs a real professional unit)

Video projection up to 12 m, which projector to by?

Hi,
I am really not an expert in video projectors, and I don't know where to start. I need a projector for a clothing store where still images and video clips would play on a wall. The problem is that we can't hang the device on the ceiling, so it has to be placed on the opposite wall, up heigh and the projection should be done from about 12m on a wall about 4x6m. Is it possible?
Or
If we install the projector on the ceiling, and we project the video clips from a 40-50 degree angle, is there a way to get a nice picture (maybe by fixing distortion in the settings) even if the projector is not set straight?
I would appreciate any suggestion. Thanks!

Depending how big an image you want you might be better to use a flat screen TV. If you use a projector (unless the light level in the store low) you will need a special screen ($$) to reject ambient light or a very bright (high lumen rating) projector (or both). Furthermore, anyone between the projector and the screen will block the screen so the suggested setup is problematic on several counts.
As to mounting you don't specify a projector so I'll assume it has yet to be acquired. That's good.
It's possible to mount a projector high on a wall if the projector has a feature called "lens shift" ... in essence the ability to adjust where the image ends up (lens shift typically allows the image to moved up and down or left to right by at least half a screen width/height). Many DLP-based (vs LCD) projectors have very limited adjustment possibility and would be a poor choice for your needs.
The biggest issue will be brightness at the distance you are planning. Most home projectors can fill a 100" screen from between about 4 and 7m ... but at 12m the image is going to be quite large (and therefore dim) ... or you will need an optional lens that will probably cost extra..
I'm afraid you may be looking at a fairly expensive proposition for a projector that will be bright enough and has a lens that allows a reasonable size image at 12m. It's possible, but, as I said, likely expensive.
See the link for a list projectors that that meet your basic requirements (You can explore further).
On the other hand, if you ceiling mount most projectors are designed to project the image down at a steep angle ... and this would be the best approach for you since a) it (at least partially) solves the customers getting in the way of the image problem, and b) it gives you a much wider choice of projectors. Again use the search engine at the link and then read reviews, etc.
