How do you add an AO lamp in an already iluminated scene who is missing some Ambiant occlusion?

One who only add the AO if possible.

    You could use pwSurface for the surface shader, which has AO on the surfaces only. Or you could render once, without AO, then set all your surfaces to white, delete your lights, load uberEnvironment in AO mode with high quality settings, render that at the same size and add it as a new layer set to Multiply over the full render in your image editor to add the AO, varying the opacity to adjust the strength. I don't think you could add AO without adding a new light that would affect the total illumination of the scene.

    One thing I forgot -you want the non-occluded areas of the AO render to be white when using it as a multiplier - white on a multiply layer leaves the underlying pixels unchanged, which is your goal. You will probably need to apply an adjustment to achieve that - you may be able to do it via a levels/equalisation adjustment layer applied to the AOK level and clipped/grouped so it doesn't modify the colour layer, but if your editor doesn't do that you can adjust it before aplying the layer; in Photoshop at least you could probably use the advanced blending options for the layer to exclude the brighter pixels entirely and just use a smooth transition into the darker pixels to modify the colour render.

    I would use the Advanced Ambient Light by Ageofarmour.

    Use it for both AO and ambient lighting and adjust your lights.

    Rendering AO in the lights via the AAL is much faster then surface based AO.

    I use darken only and play with the transparency if I want to ad shadows by multy rendering and compositing, but I'll try multiply just to see if the result is better.

    Advanced Ambient Light sent me a missing file message when I tryed to use it 2 days ago when trying to understand light in DS.

    DS dont find this file aparently
    /data/Age of Armour/Advanced Ambient Light/AoA_AmbientLight/Advanced Ambient Light.dsf

    I have no idea what I am supose to reinstal in case it was an instalation error.

    Does "Advanced Ambient Light.dsf" exist anywhere on your system?

    Nop, searching my all computer whit windows search tool get no matches.

    But I have a "CharLightBright" with "AOA light" labeled in the preview image under light preset that is asking for it so I assumed that's what he was talking about.

    Do you actually have the AoA Advanced Ambient Light? It isn't included with DS, it's an additional product in the store. You may have a preset that was supplied with something else, for use by people with the light, but not the light itself.
