Installing old Titanium SDK

I just install Appcelerator in MAC and it works find. but i also need to install sdk 4.0.0.GA

I tried few ways 1. I tried to install using appcelerator studio help > install appcelerator sdk > install from update stream > SDK build, but I don't fine any option further

1. I also try to get the directory from git hub and past in /library/application support/ titanium/ 4.0.0.GA, NOT working

Appreciate any support.

Thanks.
