I don't know if anyone may have the link or not, but I was hoping to get the older version of Outliner for 2010-2012, but they seem to be offline on the official site.
Outliner 2 works perfectly for me in Max 2014/2015
I do not use the install routines though, i simply copy the script folders over from the old installs. So i do not know if the installer is able to deal correctly with the changed folder structure in Max 2013/2014/2015
Outliner was too slow for me, I switched to Nested Layer Manager. It's still in active development, and he's in the process of rewriting it as a plugin. Not free, but it is pretty cheap.

read the remarks about building on the page and you might be able to create your own working build of Outliner ;-)
