Adding Another VST 3 Folder

I have installed a Kontact Ultimate. While installing I didn’t pay attantion to the fact that in 64 Bit all the plugs where installed into “C:\Program Files\Native Instruments\VSTPlugins 64 bit”, and nuendo of course didn’t reconized them.
In plug in manager there is option to add VST 2 path settings, but not VST 3.
How can I detour this problem please ?
Thanks in advance

Is NI now VST3 compatible? You can’t add another VST3 path so it’s unlikely that they are VST3 plug-ins if they’re not using the standard one. Add the VST2 path to your setup or re-install/move the plug-ins to your shared VST2 folder.
