The free Google Nik collection package can still be found online to download at FileHippo here: (DxO Nik Collection 1.2.15).
Thats good to know. I saw on their site they're no longer free. Nice to know they're still out there.
Older versions of many kinds of software are out there for free: Old versions of Windows, Mac and Linux Software, Apps & Abandonware Games - Download at OldVersion.com
