From the Ugly Hedge Hog Photographers Forum
Here are active links for MAC and Windows for the free Google version. Both of the links are alive.
Installer for Windows [430 MB] http://dl.google.com/edgedl/photos/nikcollection-full-1.2.11.exe
Installer for Mac [590 MB] http://dl.google.com/edgedl/photos/nikcollection-full-1.2.11.dmg
Keep in mind there isn't any support for this version. I'd recommend saving the install file. Who can say how much longer these links will last.
