OK, thanks. I have not been able to find any download link for the exe, but after some googling, I found
this. So now I have the exe. But I don't think that my old Nvidia graphic card supports the NVEnc hardware acceleration. Only cuda. So, it will be difficult for me to test NVEnc. Furthermore, I have read often that the quality of the encoding is very bad. So, I'm not sure anymore that I want to implement it. But I will do some tests anyway. But first things first. I will release a beta with the support for Avisynth+ 64-bit immediately...
