Download key generator for Nik Software Complete collection 64 Bit December 2010
This is the latest Nik software collection, updated Dec.2010
Works on Cs5, Aperture, (lightroom version included but not tested).
All sn works, Must be blocked with Little snitch, just in case.
When you install-> make sure, you do not run CS5, Aperture..etc
I have noticed only one problem with sharpener pro in Aperture: Raw presharpener works only 32 bit. Output sharpener is 64bit.
