The kontakt8player vst do not be installed and only application( I can use kontakt8player(stand alone).But the file not be intalled in my computer,and there is no vst installation paths
That is because you no longer need extra paths - VST2 plugins are now officially retired and do not ship with any NI product. There is no need for those extra paths.
Kontakt 8 (along with all other NI product) ships in the VST3 format and automatically gets installed to:
C:\Program Files\Common Files\VST3.
