I only see the light version of ZensphereUpdated 6 days ago

The installer adds two plugins, a Light version and a Dark version. They are separate items in your DAW's plugin list.

Load Zensphere Dark from that list. The white skin is the Light plugin, not a setting inside it.

Each version needs its sample folder set once. If the Dark version is silent, use the same sample-library steps as in Zensphere makes no sound.
