Windows and LINUX, same image got different NFIQ2 score, why? Both are 64-bit. image

Almost certainly, you are using your own copy of OpenCV that you build, which likely does not turn off all the optimizations and liberties OpenCV takes. We test NFIQ 2 on millions of images on all supported platforms and show no differences.

I am using your 64-bit release libraries. On windows, I used Nfiq2Api.dll. and on LINUX I used -lnfiq2 -lFRFXLL_static -lopencv_ml -lopencv_imgproc -lopencv_core Does this matter?

You are not, because as we established in #367 (now an issue in #368), we accidentally didn't include OpenCV libraries. We need to fix this.
