how to install add-ons?

How do you install an add-on into blender? I’ve read this article:

http://wiki.blender.org/index.php/Doc:2.6/Manual/Extensions/Python/Add-Ons#Installation_of_an_Add-On

but I couldn’t find the add-on I want to install in the Install Add-On tab, nor could I find the Blender configuration folder for manual installation. This is the add-on I want to install:

I have Blender 2.72b on Mac

Hello
sorry I don’t use such operating system; in my Gnu/Linux/Debian system, I’ve manually installed the last Blender version, so this is the “add-ons” folder path:
/home/Blender-2.72/2.72/scripts/addons
And this is the path of the Blender version installed by Debian ( 2.63):
/usr/lib/blender/scripts/addons
Search for something similar in your system, maybe, and just copy the scripts into the “addons” directory.
Bye

OSX version?
Anyway, it goes this way
Macintosh HD/Users/<username>/Library/Application Support/Blender/2.72/scripts/addons
Apple made user’r library hidden, among other folders… damn.
Apple menu “Go”, write the path and go there.
I suggest to go there
Macintosh HD/Users/<username>/Library/
and drag this folder to favorites (finder)

more advanced but easy
open terminal and write the following command
chflags nohidden ~/Library/
As it says, Library is not hidden any more
…until the next OSX upgrade (LOL)

Ah, I see! Thank you, helped a lot :slight_smile:
