Keyshot - how to trial version in ZW3D

Hello,

I am trying to evaluate the KeyShot add-on for ZW3D. I downloaded the trial version from the KeyShot website (as linked by ZWSOFT), but it only launches as standalone software.

The KeyShot plugin is completely missing from the Apps tab in ZW3D. How can I test the direct integration between ZW3D and KeyShot without purchasing a full license first?

Thank you,
Vojtech
