NIK 3 has been running perfectly on my Lenovo P1, in CS6 extended. After installing NIK 4, all other modules work, but I get a “not enough memory (RAM)” error with Viveza and Silver Efex. Viveza and SilverEfex do work fine outside of CS6, but not in CS6. I reverted to NIK 3, and everything works again. Is NIK4 compatible with PS CS6? My P1 is running Windows 10 pro, with 32GB ram and NVIDIA Quadro P2000.graphics.
