Aeotec Z-Stick 7 setup

Newbie here… My HA Yellow is set up and responsive. I understand that my Z-Stick 7 (added for Zwave support) needs a firmware update in the correct order. I’ve gone down a rabbit hole installing Simplicity Studio to accomplish this, but while it recognizes the Z-Stick, it won’t allow me to install firmware.

I guess my questions are 1) Am I going down the correct road at the moment, and 2) If so, how do I fix this issue, and if not, can someone redirect me?

Thanks ahead of time!

You can install firmware directly from home assistant. Aeotec has this guide on how to do so on their website. Update Z-Stick 7 with Z-WaveJS UI (V7.18.8 ->V7.21.6) : Aeotec Help Desk
