Using Cutting Muster Plugin with Illustrator 2025. Can't get it to install. iOS Ventura

I have recently updated Illustrator to 2025 as have all of the designers at my work.

We use a Graphtec Plotter and the Cutting Master plugin will not install into the updated AI 2025.

Has anyone figured how to do this, it has been fine with AI 2024. Do I have to un-install 2024 before continuing?
