I was able to find out that I should use:
Nikon DBase for NEF v3.0.0.3001


But, I still dont understand why images are different in preview and after
raw conversion is applied,

in original nikon software (with profiles applied) images look exactly
like in preview in digicam,

> AdobeRGG in mode II (for editing)
> Default is mode IIIa. This is what I use.
