I do not care about StaxRip. 
a. If you change out tools make sure to reset the tool cache. Hybrid does not check all tools on each start.
b. If Hybrid doesn't detect your card as NVEnc compatible this will be reported in the log and NVEnc will not be made available.
c. If you don't rename the NVEncC64.exe to NVEncC.exe Hybrid will ignore it.

Ps.: Its not advised to install StaxRip and Hybrid on the same system since StaxRip installs Vapoursynth and Avisynth system wide while Hybrid uses portable versions and sometimes portable and system wide installations can interfere with another. (this has nothing to do with the NVEnc problem)
